摘要

介绍了变容调谐陷波滤波器的设计过程。该滤波器为必须抑制大干扰信号的ECM应用提供了所需的速度和敏捷性。该电路是基于变容调谐微带谐振器的。边缘耦合到信号传输线。描述了一种三级滤波器，它在不到5微秒的时间内调谐到1070和1240 MHz之间的任何频率。它具有100mhz的1db带宽，20mhz的20db带宽和10mw的RF功率能力。

High Speed Varactor Tuned Notch Filter

A design procedure for a varactor tuned notch filter is presented. The filter provides speed and agility required for ECM applications where a large interfering signal must be suppressed. The circuit is based on varactor tuned microstrip resonator which is. edge coupled to the signal transmission line. A three stage filter is described which tunes to any frequency between 1070 and 1240 MHz in less than 5 microseconds. It has a 1 dB bandwidth of 100 MHz, a 20 dB bandwidth of 20 MHz, and an RF power capability of 10 mW.
