Design and Implementation of a Digitally Anti-jamming Agile Tracking Preselected Filter for Ultra Short Wave

摘要：

Design of a digitally tunable tracking preselected filter to improve the performance of antiinterference in Ultra short wave communication receiver is proposed in this paper and characteristics of the preselected filter circuit are analyzed. Then we mainly discuss the specific scheme and realization of the digitally tunable tracking preselected filter. Finally, circuit simulations and test results are provided, showing the performance indicators completely meet the needed design requirements.
