摘要

提出了一种低损耗、可调谐的二阶带通滤波器，覆盖范围为2.2-4.2 GHz。该滤波器基于倏逝模腔谐振器，由低成本的ABS塑料CNC加工而成。该滤波器的插入损耗为0.77 ~ 0.26 dB, 3db分数带宽为8.4% ~ 9.1%。在调谐范围内，谐振器的提取空载质量因子(Q)为500-700。

A 2.2–4.2 GHz low-loss tunable bandpass filter based on low cost manufacturing of ABS polymer

A low loss, tunable, second order, bandpass filter covering the range 2.2–4.2 GHz is presented. The filter is based on evanescent-mode cavity resonators and manufactured by CNC machining of low cost acrylonitrile-butadiene-styrene (ABS) plastic. The filter has an insertion loss from 0.77–0.26 dB, with a 3-dB fractional bandwidth from 8.4% to 9.1%. The extracted unloaded quality factor (Q) of the resonators is 500–700 over the tuning range.
