摘要
基于频带分割方法,利用带通(或带阻)滤波器的带外抑制性和三端口环行器的定向传输性,提出了一种新的异频合路器设计方案。该合路器原理通用性强,软件仿真和实物测试结果表明:在排除各器件自身损耗和滤波器带外抑制度小于-30 dBc条件下,该合路器能够不失真地同时传输多频具有不同带宽的信号,具有应用于有源相控阵T/R组件中实现同时多功能的潜力。
Based on the band-share method, by using of the stop-band suppression of the hand-pass filter and directional transmission of the microwave circulator, a microwave combiner design is put forward in this paper. Simulation and sample test manifest：on condition that the loss of all the units themselves is eliminated, and the suppression of the filter is less than -30 dBc, this combiner can simultaneously transmit multiple-frequency signals without distortion. So this combiner has the potential to be used in T/R module of Active Electronically Scanned Array（AESA） for achieving simultaneous multifunction.
