This paper presents an improved sampling-based down conversion topology design with double RF filters for multi-standard RF subsampling receiver. Proposed architecture is limiting down conversion to IF domain and adding a first tunable RF filter to select multistandard RF bands. To overcome subsampling negative effects on receiver performances a second RF filter is inserted before subsampling operation to perform anti-aliasing and limit wide band noise. RF filters design methodology and ADS simulation results are presented for GSM, UMTS and IEEE-802.11g standards. Good performance improvement is obtained with reduced complexity architecture and circuits
