VHF high-power tunable RF bandpass filter using microelectromechanical (MEM) microrelays

This is the authors' abstract. We don't add key points for this paper.

A VHF RF bandpass filter tuned through the use of MEM microrelays was operated at a 25 W RF power input level. The filter insertion loss was less than 1 dB at the tuned frequencies of operation, and the filter operating Q was about 10. The MEM microrelays were life tested for 53 million operating cycles at 25 W RF power, and no significant degradation to the contacts was noted. The development of the microrelay and the use of a CAE tool in the filter development are discussed.
