Description

A kind of waveguide duplexer of built-in waveguide junction circulator

Technical field

The utility model belongs to technical field of micro communication, particularly a kind of high integrated waveguide duplexer.

Background technology

Digital microwave receive-transmit system structure is generally that antenna wave guide piece is connected with waveguide junction circulator, two other port of waveguide junction circulator respectively with independently transmission channel filter, receive path filter cavity mechanical connection separately.The shortcoming of said structure scheme is: filter and circulator mechanical connection, when connection, there is mechanical tolerance, when production in enormous quantities, precision is difficult to coupling unanimously, this stacked structure, the machinery assembling accumulated tolerance of generation can cause fitting surface dislocation or tilt, and affects the coplanar and coaxial requirement of microwave components, particularly produce in assembling at high-frequency microwave parts, will cause more serious microwave transmission impact, affect the overall performance of microwave telecommunication system, when serious, can cause system works not smooth.In addition, this kind of organization plan, overall structure is bigger than normal, can not meet system miniaturization demand, simultaneously high expensive.

Utility model content

The purpose of this utility model is that the shortcoming that overcomes prior art is with not enough, a kind of high integrated waveguide duplexer is provided, adopt the waveguide duplexer of this built-in waveguide junction circulator, can be without waveguide junction circulator and filter mechanical connection in microwave telecommunication system Assembling Production process, solve the matching problem between filter and waveguide junction circulator, ensure the consistency of microwave system performance, simultaneously built-in evaporative pattern waveguide filter in waveguide duplexer cavity, can suppress higher mode, improve the overall performance of this device.

The utility model is realized by the following technical solutions:

A kind of waveguide duplexer of built-in waveguide junction circulator, built-in waveguide junction circulator in transceiver channel common port (being antenna end) cavity in described waveguide duplexer, waveguide junction circulator adopts single or double magnetization configuration, and standing wave and the isolation of waveguide junction circulator are adjustable; The each built-in evaporative pattern waveguide filter of transceiver channel of waveguide duplexer is used for suppressing higher mode.This waveguide duplexer is simple in structure, and integrated level is high, is convenient to produce and installs.

The utility model compared with prior art beneficial effect is: the utility model, by built-in circulator in the transceiver channel filter common port cavity of waveguide duplexer, has been avoided the mechanical connection of filter cavity and waveguide junction circulator; Waveguide junction circulator standing wave and isolation are adjustable simultaneously, have solved a matching connection difficult problem for transceiver channel filter in waveguide junction circulator and waveguide duplexer; The built-in evaporative pattern waveguide filter of waveguide duplexer transceiver channel has effectively been eliminated outside band and high-end clutter; This structure has ensured that system connects and the consistency of performance, and this diplexer structure is simple, and integrated level is high, is convenient to produce and installs.
