【摘要】 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%。更多还原

【Abstract】 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 analyzer 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.更多还原
