摘要
描述了一种使用HTS/AuMEMS 开关电容器阵的低插损电子调谐式滤波器。同步将每个谐振器的电容值以相同变化量变化,两极滤波器就得到调谐。单极谐振器在3500~5000之间的K 系数得到了证明。在77K 平均Q 值为7000 时的总调谐范围大约为25%。
A low loss electronically tunable filter was demonstrated using HTS/Au MEMS switched capacitor arrays.The two-pole filter was tuned by simultaneously varying the capacitance of each resonator by equal amounts.A K factor of between3,500and 5,000 was demonstrated for single pole resonators. The total tuning range was about 25% with an average Q of 7,000 at 77 K.
