Abstract

This paper reports development of an integrated tunable filter for lower UHF band based on the recursive architecture and its application. The recursive filter core gives the 2-pole bandpass response, and its center frequency can be tuned from 250 to 500 [MHz]. The auto setting mechanism was developed for the filter center frequency and passband width. Higher order filters were synthesized by combining multiple cores. A simple spectrum scope was constructed as a demonstration.
