本文阐述新近开发的采用微带线环形谐振腔可调带通滤波器的基本特性和实验结果。实验的滤波器较普通的滤波器有更陡的衰减曲线和更好的电路稳定性,它看来很适合作MIC和MMIC的滤波器。
This article describes the newly developed basic characteristics and experimental results of a tunable bandpass filter using a microstrip loop resonator. The experimental filter has a steeper decay curve and better circuit stability than the ordinary filter, and it appears to be well suited as a filter for MIC and MMIC.
