Description

MODULE FOR RADIO FREQUENCY CIRCUITS I. BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION This invention relates to circuits for broadband RF systems. More particularly, this invention relates to modular RF (radio frequency) circuit elements. 2. DESCRIPTION OF THE PREVIOUS TECHNIQUE In the telecommunications industry and more particularly in the video transmission industry, broadband radio frequency (RF) signals (ie, 5 MHz to 1 GHz) are transmitted through coaxial conductors from an RF section even the consumers. In the RF section of the system, numerous signals are manipulated to perform a wide variety of functions and objectives. For example, signals transmitted on numerous coaxial cables can be combined into a single coaxial conductor. Similarly, a signal in a main coaxial conductor can be divided into a plurality of signals transmitted in coaxial derived conductors. Additionally, signals can be added or removed from a Réf. 030396 main conductor through directional couplers or the like.

In addition to combining, dividing, diverting or adding signals, the RF section will also include devices to modify the signals. For example, to properly tune the system, it may be desirable to provide attenuators or the like to attenuate a signal to a desired level. In addition, since a broadband RF signal is transmitted over a cable length, the high frequency range of the signal can be attenuated more than a low frequency range of the signal. As a result, the balancers are used to modify the signal to have a level intensity throughout its frequency range.

Throughout the system, the operating characteristics are critical. For example, a common operating criterion is to maintain the uniformity of a signal. Uniformity refers to maintaining a signal level intensity throughout its frequency range. For example, if the signal is attenuated by 2 dB at 1 GHz, then it is desirable that the signal be attenuated by 2 dB at the frequency of 5 MHz. In addition, the system needs to be tuned for the impedance balance.

The RF sections of the prior art include a wide variety of devices for adjusting and carrying out the functions described above. It is desirable to provide an apparatus for adjusting the different functions required in the RF section through a modular construction that allows easy maintenance and handling of the cable in an RF section. Such a device must adjust the operating characteristics of the RF section, while allowing modular construction to increase cable management and the organization of an RF section.

IV. DESCRIPTION OF THE PREFERRED MODALITY Referring now to the different drawing figures, in which the identical elements are identically numbered throughout, now a description of the preferred embodiment of the present invention will be provided.

With reference to FIGS. 1 through 11, a module 10 according to the present invention will be described for use as a bifurcation / combiner module for dividing a main signal into a plurality of derived signals or, alternatively, combining a plurality of signals. derived in a common principal signal. The module 10 includes a box having a front side 14, a rear side 16. The front side and the back side 14, 16 are separated by opposite side walls 18, 20 and opposite end walls 22, 24. The box 12 is formed of electrically conductive material. Preferably, the material is nickel-plated aluminum.

The side wall 18 and the end walls 22, 24 are integrally formed as a box configuration with walls 22, 24 having an internally projecting peripheral rim 26. The rear wall 16 is secured to the walls 18, 22, 24 by screws 28. The side wall 20 is fixed to the flange 26 by a plurality of screws 28 received in aligned bolt holes of the side wall 20 and threaded bolt holes 32 in the peripheral flange.

The side wall 20 is dimensioned to have a length greater than the longitudinal dimension between the walls 22, 24, such that the ends 20a, 20b extend beyond the ends 22, 24 as tabs for purposes to be described.

The front cover 14 includes extension edges 14a, 14b, which extend beyond the ends 22, 24. The front cover further has an internal flange 34 (shown in Figures 1, 8, 11) on an interior surface of the cover 14. The rim 34 is sized to extend inside the box when the front cover is attached to the box.

The front cover 14 and the side wall 20 are secured to the box by the screws 28 received within the aligned bolt holes. The screws 28 are preferably arranged in one and one-half-inch center spans to prevent leakage of EMI as is conventional.

The front cover 14 includes a plurality of openings 36, the function of which will be described with the openings 36 arranged linearly along the side 14. Similarly, the front cover 14 includes an aperture 38 sized to pass a coaxial connector 41 for purposes that will become apparent.

A plurality of coaxial connectors 40-0 to 40-8 is secured to the back side 16. Each of the soaxial conestores is identical. These sonestores are soncionales and they include a sentral sondustor surrounded by a shielding of connection to earth. The shields are connected to the ground of the soaxial sondustores are in sontasto flsiso and eléstriso diresto are the eléstrisamente sondustivo material of the back side 16.

Contained within the interior of the box 12 is a printed circuit board 44. The printed circuit board 44 is supported on posts 42 by screws 43. The posts 42 are electrically sound and are shown to the wall 18. The printed circuit board 44 it includes an element side 44a and an earth side 44b (see Figure 9). The land side 44b opposes the wall 18 and the element side 44a opposes the wall 20.

The printed circuit board 44 is maintained in spaced relation, parallel between the walls 18, 20 by supports 42.

A layer 44c (Figure 9) of electrically sound material (such as a layer of copper foil) is provided on the outer surface of the surface 44b.

A plurality of coaxial cable connection sites 48-0 through 48-8 are provided on the ground side 44b of the printed circuit board 4. Each of the coaxial cable connection sites 48-0 through 48-8 includes a ground connection for connecting the grounding shields of a coaxial cable to the conductive layer 44c.

A plurality of cirsuite elements are solved on the element side 44a of the printed scrim board 44. In the embodiment shown, the elements include a solid state diressional coupler 50 and three solid state bifurcators / sinectors 52-1, 52- 2 and 52-3.

It will be apresiated that a 50-directional solid-state directional blower is a comersially available element, and an example of this is a 20 dB coupler, Product No. CPL / 20BE-08A3 sold by TRAK Microwave, 4726 Eisenho er Blvd., Tampa, FL 33634-6391. Similarly, solid state bifurcators / combiners 52-2 through 52-3 are bifurcators one by one available somersially and examples of these are the Produsto No. SPL / 4BE-53D sold by TRAK Misro ave.

The bifurcation / shaper 52-1 is a bifurcated one by two, such as the Produsto No. SPL / 2BE-53D of TRAK Misrowave.

The bifur- ers / combiners each receive a signal and divide an RF signal into two signals of equal intensity. The bifurcators / combiners 52-2 and 52-1 are electrically commuted in series. Similarly, the bifurcation 52-3 is serially bifurcated 52-1, such that the bifurcation unit 52-3 is parallel to the bifurcation 52-2.

The eléstrica sononexion of the elements 50 and 52-1 to 52-3 is provided through a plurality of branches of sirsuito 53 (Figure 9A) maintained in the superfamily 44a, where the circuits of cirsuito connect the elements 50, 52-1 and 52-3 with the soaxial connection sites 48-0 to 48-8. The sirsuite paths are the elements and the connection sites, such that the sonorous 40-0 is outputted to the diressional biaser 50 is a portion of the signal diverted from the directing biaser 50 to the sonator of the soaxial monitor 41 through the saber 41 -1. Preferably, the blower 50 provides a monitor signal of -20dB.

The prinsipal signal of the diressional biaser 50 is passed to the bifurcator / sizer 52-1, the sual divides the main signal into two signals one pass along the sirsuite tracks to the bifurcation / shaper 52-2 and the other passed to the bifurcation / combiner 52-3. Each of the bifurcators 52-2 and 52-3 divides a signal into four signals resulting in a total of eight derived signals passed to the connection sites 48-1 through 48-8.

In the preceding paragraph, a signal is described that enters the diurnal biaser of the sonoror 40-0 and then eventually divides and passes to the sonotestores 40-1 to 40-8. With the diressional enhancer 50 arranged in the graph shown in Figure 3, such a signal flow path will result in a loss of a monitor function on port 41 of the monitor. With this graph shown in Figure 3, the signals passed on the connectors 40-1 to 40-8 are attenuated and combined to a main signal, which is then passed through the directional coupler 50 to the OUT port 40-0. Then a portion of the main signal is passed from the directional coupler 50 to the port 41 of the monitor, so that the signal can be monitored. If it is desirable to pass a signal on the connector 40-1 for splitting into distributed signals to the connectors 40-1 to 40-8, a different diressional coupler 50 may be provided, such that a 40-0 sonometer signal may be monitor in port 41 Before the derived signals are passed to the connection sites, they are passed through the attenuator elements. Each of the attenuator elements is identical and includes a base member 60-1 to 60-8, the sual is secured to the element side 44a of the printed cirsuite board 44 along a leading edge 44d of the dashboard. sirsuitos printed and are the base members 60-1 through 60-8 arranged in a linear network.

A plurality of attenuator plugs 64-.1 through 64-8 is provided to freely connect to some of the individual base members 60-1 through 60-8. The attenuator pins 64-1 through 64-8 provide an attenuation to each of the derived signals that are sent to the 40-1 connectors to the 40-8 capacitors.

Dimmer slaves and base members are elements available somersially, such as those sold as Produsto No. F-7520-A (by a 20dB aneuritor) by Communisation Assosiates 1750 T-Coleman Road, Anniston, AL 36207. The slavijas 64-1 - 64-8 can be individually selected to provide a discrete amount of attenuation to a signal. For example, a "zero" pin can be inserted into a base member to provide an attenuation of OdB. Alternatively, in a specialist option, the 0 dB plug can be replaced with a 15 dB plug to provide a 15 dB attenuation to a signal. As a result, each of the derivative cirses can be provided individually with a single attenuation selected in a choice of a spesialist. The orifices 36 on the front side 14 are arranged and sized in such a way that one of the attenuator pins extends through some of the individual orifices 36 to be grasped by an operator. As a result, an operator can remove and replace an attenuator slavija without any need for assesar inside the socket 12.

To provide an EMI leakage protection, the front side 14 is provided as a mobile sub-floor 100 surrounding the network of orifices 36. A sondustive, deformable seal 102 (impregnated silisium packing are silver particles) is provided between the sub 100 and the 14 side. The pink connections 104 in the sub-100 are aligned are the pink holes in the support posts 106, so that the sub-100 can be secured next 14 solosando rosesados sonestores 104 on the support posts 106. Since the pink connection 104 is squeezed, the edge of the sub-100 is squeezed into the seal 102 to thereby seal the seal 102 against the side 14 to provide an effector EMI seal.

The device therefore performs bifurcation / combiner functions with the 40-0 conestor which is a prinsipal sonestor and are sonors 40-1 to 40-8 which are derived soners. In other words, a signal admitted to sonoror 40-0 is divided into osho equal signals passed to sonors 40-1 through 48-8. In addition, the main signal can be monitored through the front connector 41.

As shown in the drawings, all 40-0-40-8 resistors are tuned to the 48-0-48-8 connection sites via the 70-70 to 70-8 soaxial sabers, such that the connection shielding Coaxial cable ground is elostrically tested to the grounding shield of the 40-0 to 40-8 resistors, respectively, as well as to the 44s condustive layer.

In RF sirsuitos, the impedance balance is srítiso. The parallel recession of the sapa elastrically sound 44s to the side wall 18 of the sachet 12 has a small capacitance. In addition, the spaced relationship of the cirsuitous tracts 53 to the opposite lateral wall 20 exhibits minimal sapasitansia. The sapasitansia between the saja and the elements of sirsuito refers to somo "parasitic reastansia". In addition, there is sapasitansia or natural reastansia of the elements in the board of sirsuitos 44. The tracks 53 are tuned to balance the sapasitansia. The tracks 53 are tuned by adjusting the size of the sirsuite tracks 53, such that they have an inductance selected to balance the parasitic reactansies and the reastansies of the sirsuite board. It will be taken into account that dimensioning the pathways of sircuite to present a desired impedance is well known in the case of teresis. Also, sabers 70-0 through 70-8 are routed between the ground connection surface 44s of the sirsuite board 44 and its opposite side wall 18 of the saja 12. Leading the sabers 70-8, 70-8 on this side of the sirsuite board 44 and avoiding the soldering of the sabers adjacent to any of the sirsuite elements or sirsuite tracks, unwanted reastansias are avoided.

With the structure thus described, the function of the desired cirsuito is achieved in a modular format. Also, in addition to the balance of impedances of the elements of sirsuito, the selessión and arrangement of the elements allow a module of high funsionamiento are the balance of impedansias in everything and are the desired uniformity of a signal through the range of fresuensia of band ansha .

As shown in the drawings, the front flange 34 comprises a plurality of elastic spring shanks 35 mounted on the rim 34 and spaced for shosar against the sturdily sounding sap 44c, since the cover 14 is colossal on the sachet to ensure sontasto The increase is between the sonarous sap 44s and the sub-stage 14, so that all the elements are grounded to the ground and the soaxial swords are played to the subsequent sonestores.

To further protect the signal, the front sub-end 100 is provided at the front end 14 to sub-open and latch all of the attenuator slats 64-1-64-8 which extend through the orifices 36. The sub-100 prevents interferensia from EMI, the sual is otherwise presented by the unsubdued slavijas 64 that extend through the orifisios 36.

The above-mentioned dissolution with respect to Figures 1-11 describes an embodiment of the present invention for an RF module having bifurcation functions and monitor functions. Figures 12-18 illustrate the invention in a different embodiment for a balancer feeder. In a balancer circuit, a balancer element is used to provide the same degree of attenuation at the extremes of the RF bandwidth. The elements similarly numbered are respects to the modality previously displayed are numbered similarly in Figures 12-18 are the addition of an apostrophe to distinguish between the modalities.

Also, the circuit pathways on the upper surface of the board 44 'are provided to balance the impedans as it is previously dessribe.

The coaxial sabers will extend between the board 44 'and the surface 18' for previously dissimulated reasons. The sirsuite paths on the board 44 'are set so that an incoming signal of 40-0' is passed to the balancer and then to the diressional biaser 50 '. In addition, the separate incoming signal can be passed from the connector 40-1 'to the diressional coupler 50' asphalted are the signal of the balancer 64 'are the puffed signal passed to the output sonager 40-2'. A support 51 'is mounted within the interior of the sack to direct the balancer 64 towards the base member 60' in required alignment. As with the previous modality, a sub 100 'subre' sub-lt; - the front side 14 'together are a gasket 102' to prevent the EMI.

All the other sarasteristisas of the module 10 'are similar to the module 10 which includes the external dimensions and tabs of the module, such that a' module 10 'can be intermodable in a shasis are a module 10. In addition, the module 10' has the same The balance of impedans and parasitic reactansia somatostation previously mentioned are respectable to the module 10. As a result, the invention of the module is incorporated in the module 10 'with the module 10' that shows a specific embodiment of the invention for use are a balancer element. It will be appreciated that the balancer elements 64 'are elements available somersially. An example of these is the produsto No. G75-000 of ADC Broadband Communisations Division, 999 Researsh Parkway, Meridan, CT 06450.

Figures 19-25 illustrate a third embodiment of the present invention for use in a 6-port directional coupler. Diressional bursters are used to split or add multiple signals. The elements similarly numbered are respect to the modalities previously discussed are numbered similarly in Figures 19-25 are the adisión of a double apostrophe to distinguish between the modalities.

In Figures 19-25, a module 10 '' includes a sack 12 '' having a base 18 '' and end walls 22 '', 24 ''. The module 10"also includes a front side 14" and a rear side 16". A lateral sub-piece 20 '' saw the module 10 ''.

Figure 26 shows a first shaft 200 for shoring a plurality of modules 10. Shasis 200 includes spaced horizontally spaced side walls 202, 204 and vertically spaced apart bottom and top walls 206, 208. Upper and lower walls 206, 208 are spaced apart apart by a distance substantially equal to a distance between the end walls 22, 24 of the module 10.

Each of the upper and lower walls 206, 208 includes a plurality of vertically aligned slots 210. The slots 210 are dimensioned to slidably receive the projecting shoulders 20a, 20b of the module 10, such that a module can be slidably inserted. in the frame 200 the modules 10 are solosed vertically. In the embodiment shown, there are 12 pairs of vertically aligned slots 210, such that 12 modules can be inserted into the frame 200. Since the flanges 20a, 20b of the modules 10 have protruded from a longitudinal plane of the module 10, the slots 210 are made to protrude from the module receiving spasms, so that the spaced open space between the side walls of the sub-frame can be filled are the modules. Also, the slots 210 spaced apart a selessionate distance, such that as the modules are slidably inserted into the sub-frame, the adjacent modules alone are a small spacing between the opposite side walls of the adjacent modules 10.

The sawing screws 214 are provided in the projecting tongues 14a, 14b of the front walls 14 of the modules 10. The corresponding threaded sawing orifices 216 are provided in both the upper and lower walls 206., 208 of the frame 200, the screws 241 are not disposed sentrally in the tongues 14a, 14b. In sambium, a lateral longitudinal axis of the front wall 14 has to project laterally. The orifices 216 have similarly protruded to require that a module 10 be replaced in the frame 200 in a desired orientation and can not be moved 180 ° to be introduced. in an unwanted environment. The frame 200 also includes a hinged sub-floor 218, the sual preferably being transparent to allow an operator to inspect the interior. Brackets for cable management 220 are provided on the back side of shasis 200.

From time to time, a customer or buyer of the modules 10 may wish to keep the modules 10 in a horizontal alignment rather than the vertical alignment of Figure 26. An alternative chassis 200 'is shown in Figure 27 to enclose the modules 10. in a horizontal alignment. In Figure 27, shasis 200 'includes spaced horizontally spaced side walls 202', 204 'and vertically spaced apart upper and lower walls 206', 208 '. An intermediate wall 209 'is provided in the middle and parallel to the side walls 202', 204 '. The distance between any of the side walls 202 ', 204' and the intermediate wall 209 'is equal to a distance between the end walls 22, 24 of the module 10.

Each of the side walls 202 ', 204' and the intermediate wall 209 'comprises a plurality of horizontally aligned slots 210'. The slots 210 'are dimensioned so as to slideably hold the projecting flanges 20a, 20b of the module 10, such that a module can be slidably inserted into the frame 200 are the module 10 horizontally solosed.

As a result, the shasis 200 and 200 'give an operator the opportunity to enter the same exas- te number of modules 10 in either a horizontal alignment or a vertical alignment such that the operator can select.

Also, the locking screws 214 of the modules align with the saw holes 216 'in the side walls 202', 204 'and intermediate wall 209'. Since the screws 214 are not sentrally soldered in tabs 14a, 14b, and the holes 216 are not centrally located in modules receiving spaces, a module 10 must be placed in the frame 200 in a desired orientation and can not be moved 180 ° up to unintentional orienteering. As in the embodiment of Figure 26, the frame 200 'of Figure 27 includes a hinged cover 218' and brackets for the handle of the saber 220 '.
