针对当前双频或多频带通滤波器主要以30 GHz以内的工作范围为主,在高频毫米波范围内以单频超宽带设计为主这一现象,设计出一款可以在100 GHz~103 GHz工作范围内存在两个超窄带工作带宽的双频腔体滤波器.两个工作频段分别为100.67 GHz~101.36 GHz和102.67 GHz~102.78 GHz,与之对应的相对带宽分别为0.68%和0.11%.所设计腔体滤波器采用UV-LIGA工艺完成其样品的制备,并使用由矢量网络分析仪和扩频模块所搭建的测试平台完成测试,经测试,相对带宽的绝对误差分别为0.19%和0.02%.
Research on Design and Manufacturing Process of 100 GHz Dual-Band Pass Cavity Filter
Aiming at the phenomenon that the current dual-frequency or multi-band pass filter is mainly based on the working range within 30 GHz,and the single-frequency ultra-wideband design is the mainstay in the high-frequency millimeter wave range,a model of dual-band cavity filter that can work in the 100 GHz~103 GHz range with two operating band is designed. The two working frequency bands are 100.67 GHz~101.36 GHz and 102.67 GHz~102.78 GHz,and the corresponding relative bandwidths are 0.68% and 0.11%, respectively. The designed cavity filter is manufactured with the UV-LIGA process,and the test platform is built with the vector net ana-lyzer and the spread spectrum module to complete the test. The test results show that the absolute error of the relative bandwidth is 0.19% and 0.02% respectively.
