Abstract
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.
