Abstract
The utility model relates to a kind of distributed correlator.This circuit structure is realized by a power splitter and three λ/4 Wave coupling devices, port one (Port1) and port 2 (Port2) as input port, port 3 (Port1) to port 6 (Port6) as output port.Wherein coupler adopts open stub to realize.The utility model efficiently solves the problem of operation mistake of being correlated with when most of lumped device uses.This circuit structure is strengthened making the temperature-insensitive type of resistance, and adaptability is good, and stability is high.Meanwhile, six port correlator circuits can realize filter function in various different frequency range, and the utility model can be widely used in the system needing to use correlator.
Description
Technical field
The utility model relates to correlator, and particularly a kind of distributed six port correlators, belong to electronics and the communications field.
Background technology
Along with the development of the systems such as microwave and millimeter wave communication, radar, the especially development of mobile hand-held wireless communication terminal, satellite mobile communication terminal, military and civilian multimode multiplex communication terminal, harsh all the more to the requirement of related device in system.Wherein, a lot of lamped element due to correlator performance bad and cause the problem of system related operation mistake, terminal development speed was once slowed down.In recent years, domestic and international many researchers put forth effort to address this problem, and propose a series of solution, as RLC and active interlock circuit and transmission line interlock circuit, have promoted the development of interlock circuit to a certain extent.But in current proposed method, shortcoming is more, and the utility model adopts this correlator circuit, can realize carrying out effectively process etc. to ultra broadband.
Summary of the invention
The utility model object is that providing a kind of utilizes the plane microwave that distributed planar structure, structure are simple, stabilized susceptibility is little, volume is little, stability is high to be correlator circuit.
The technical scheme realizing the utility model object is: comprise and being realized by a power splitter and three λ/4 Wave coupling devices, port one (Port1) and port 2 (Port2) as input port, port 3 (Port1) to port 6 (Port6) as output port; Z
lconnect 50 ohmages.
Power splitter is realized by lamped element, and λ/4 Wave coupling device adopts planar structure, is realized by the single stub of open circuit; Z
lconnect 50 ohmages.
Compared with prior art, because the utility model adopts distributed planar microstrip to form, the remarkable advantage brought is: (1) bandwidth is adjustable; (3) temperature sensitivity is low; (4) volume is little; (5) stability is high; (7) frequency range is controlled; (8) applicability is extensive, is applicable in the various system strict to performance requirement.
Accompanying drawing explanation
Fig. 1 is a kind of distributed correlator configuration schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Composition graphs 1, the utility model is a kind of distributed correlator, comprise and being realized by a power splitter and three λ/4 Wave coupling devices, port one (Port1) and port 2 (Port2) as input port, port 3 (Port1) to port 6 (Port6) as output port; Z
lconnect 50 ohmages.
Power splitter is realized by lamped element, and λ/4 Wave coupling device adopts planar structure, is realized by the single stub of open circuit; Z
lconnect 50 ohmages.
Composition graphs 1, the distributed correlator of the utility model, its operation principle is summarized as follows: when the microwave signal of input enters power divider circuit through input port Port1, carry out decile generation
signal, is connected with coupler 3 with coupler 1 respectively, three
coupling line adopt open stub realize, port 2 enters input as radio frequency rf signal, port 3 (Port1) to port 6 (Port6) as output port.Can relevant parameter as required, select different stub lengths, can carry out adjustable to this correlator, this embodies one of advantage of the present utility model.
Realize by plane lamped element and open circuit microstrip stubs in the distributed correlator circuit of the utility model, processing is simple, and good stability, reliability is high.Because stub is adjustable, different forms can be adopted to realize, thus volume is significantly reduced.This correlator has fabulous performance.
