Abstract

A 75-110GHz (W band) high-Q tunable band pass filter is demonstrated. The band pass filter has low insertion loss, a Q of approximately 200 and can be tuned across the entire W waveguide band. This filter has a variety of uses including rejecting spurious signals generated from non-linear frequency multiplication and improving signal to noise ratio at the front end of a receiver. The tuning is achieved by actuating a resonant cavity by using a sub-micron resolution stepper motor.
