摘要

描述了一种由平面(Ba,Sr)TiO/sub - 3/薄膜铁电电容器电子调谐的微波四极波导滤波器。滤波器可根据直流控制电压对铁电电容的变化进行调谐。K/sub / u/波段滤波器参数如下:1 dB电平带宽为/spl sim/0.8%，调谐范围为260 MHz (/spl sim/1.8%);插入损耗小于3db。

14 GHz tunable filter based on waveguide-dielectric resonators

Described are microwave four-pole waveguide filters electronically tuned by planar (Ba,Sr)TiO/sub 3/ film ferroelectric capacitors. The filters are tuned due to variation of ferroelectric capacitance with DC controlling voltage. Parameters of K/sub u/-band filters are the following: bandwidth for 1 dB level is /spl sim/0.8%, range of tuning is 260 MHz (/spl sim/1.8%); insertion losses are less than 3 dB.
