Design and Implementation of a Digitally Tunable Tracking Preselected Filter for Ultra Short Wave Receiver

Abstract:

Design of a digitally tunable tracking preselected filter for improving anti-interference for Ultra Short Wave receiver front-end is proposed in this paper and the characteristics of the preselected filter circuit are analyzed. Then we mainly discuss an inductor-coupled dual resonant structure with better selectivity and anti-jamming and its implementation. Finally, test results are provided, shown the specifications of the circuit are in great agreement with the simulation and design requirements.
