| Abstract: | A digitally electricity tunable filter for frequency-hopping communication system RF front-end,which has advantages of lots of hopping points,fast tuning rate and excellent electrical characteristics for each hopping point. The frequency-hopping radio frequency receiver front-end system is introduced. Various forms of electricity tunable filter's performance are analyzed,and the digitally electricity tunable filter design is determined. The design of a digitally tuned filter's circuit is proposed,including ... |
