    Abstract

    An S-band frequency tunable filter chip is designed based on monolithic microwave integrated circuit technology. The channelized structure is adopted in the tunable filter chip to realize wideband frequency agility by selecting different channels. In each channel, a cascaded form of multistage amplifiers and passive filter network is adopted to improve the frequency selectivity of the filter circuit. The varactor diodes are employed in the passive filter network to achieve continuous tuning
