摘要

提出了一种利用微带环形谐振器设计的低损耗可调带通滤波器。可调性是通过使用厚膜钛酸钡锶(BST)浆料在低温共烧陶瓷(LTCC)衬底中嵌入并联并联板可变电容器来实现的。给出了滤波器在10ghz和12ghz频率下的响应、损耗和可调性的实测数据。结果表明，滤波器的插入损耗低，使用范围窄。

Tunable Rectangular Ring Resonator Filter with Embedded Shunt Barium Strontium Titanate Capacitors

Design of a low loss tunable bandpass filter using a microstrip ring resonator is presented. The tunability is achieved through the use of embedded shunt parallel plate variable capacitor implemented into the Low Temperature Cofired Ceramic (LTCC) substrate using thick film Barium Strontium Titanate (BST) paste. Measured data on the filter response, loss, and tunability in the frequency of 10 GHz and 12 GHz is presented. Results show filters produced low insertion loss with narrow tenability range.
