Abstract :
The design procedures for an electronically tuned band-stop filter are presented. A technique for realizing tunable band-stop filters with coupled lines is discussed. The physical design and electrical performance of a five-section band-stop filter tunable from 6.5 GHz to 10 GHz, with a constant bandwidth, is given. The circuit required to drive the band-stop filter and the calibration procedures are described.<>
