Description
Technical field:
The invention belongs to microwave and millimeter wave device arts, particularly relate to the duplexer in microwave and millimeter wave device.
Background technology:
Duplexer achieves wide development in mobile communication, the field such as radar.Duplexer often supports the use with antenna, and it is made
With being that signals different for two-way frequency is separated to two ports from a port, or this two paths of signals is closed from two ports
Become to a public port.Existing diplexer structure is complicated, and price is high.
Summary of the invention
The purpose of the present invention is to propose to a kind of simple in construction, the low micro-strip of price is double with substrate integration wave-guide mixed structure
Multiplexer.
The technical scheme is that
Including input matching network 11, micro-strip low-pass network 12, substrate integration wave-guide high pass network 13, input matching network 11 is
T-shaped, T-shaped the right and left minor matters are connected with substrate integration wave-guide high pass network 13, micro-strip low-pass network 12 respectively, T word
The lower end of shape is the input port of duplexer, and micro-strip low-pass network 12 is by the 1-n high resistant line 121 laterally connected, at high resistant line
1-(n-1) the open circuit minor matters 122 that junction point is the most in parallel, the first output port 123 being connected with the n-th high resistant line 121
Constituting, wherein n is more than or equal to 2, and the quantity of open circuit minor matters 122 is less than the quantity of high resistant line 121 by 1, substrate integration wave-guide high pass
Network 13 is by the rectangular waveguide coating metal 131 being positioned at substrate upper and lower surface) two row's plated-through hole arrays 132, left and right
Trapezoidal transition line 133, the second output port 134 being connected with left trapezoidal transition line, and Jie between two waveguide coating metal 131
Matter layer 2 collectively forms, and two row's plated-through hole arrays 132 run through dielectric layer 2 and are positioned at the long limit of waveguide coating metal about 131 two
Inner side, right trapezoidal transition line is connected with the left side minor matters of input matching network 11.
The kind of duplexer can be divided into cavity duplexer, dielectric duplexer and micro-strip duplexer etc..Micro-strip duplexer system
Making on circuit boards, technique is simple, and cheap, size is also much smaller than cavity duplexer.Substrate integrated waveguide technology is simultaneously
The advantage with the high-power high quality factor of metal waveguide, and the advantage that the size of microstrip line is little, more and more by people
Concern, be the most widely used in the making of the passive device such as antenna, wave filter.Simple substrate integration wave-guide leads to metal
Waveguide is the same, has the characteristic of high pass, therefore can be used to make the high pass network of duplexer, do so, can make duplexer
Simple in construction, it is simple to design.
The principle of technical solution of the present invention is:
Signal is entered by T-shaped input matching network 11, T-shaped both sides respectively with micro-strip low-pass network 12, substrate is integrated
Two networks can be mated by waveguide high pass network 13 by the length and width changing these two limits.Micro-strip low pass net
The high resistant line 121 of network can be equivalent to inductance, has the characteristic of low pass, and minor matters 122 of opening a way can produce zero point at stopband, increases low
The Out-of-band rejection level of bandpass filter, by reasonably design, can make this low-pass network produce generalized chebyshev low pass and ring
Should.Trapezoidal transition line 133 in substrate integration wave-guide high pass network 13 is for the transition of micro-strip to substrate integration wave-guide.Substrate collection
Becoming waveguide itself to have the width of the characteristic of high pass, its cut-off frequency and substrate integration wave-guide, the relative dielectric constant of substrate has
Close, and its Out-of-band rejection, being controlled by substrate integration wave-guide length, length is the longest, and Out-of-band rejection is the best.
Advantages of the present invention and beneficial effect:
(1) present invention process-cycle is short, and production cost is low, electric performance stablity, is suitable for batch production；
(2) high pass network of the present invention is directly constituted by substrate integration wave-guide, simple in construction, and design is convenient.
Accompanying drawing illustrates:
