This paper presents a multiband RF front end, designed with cascading a ultra wide band (UWB) low noise amplifier and a tunable band pass filter (BPF). The tunable BPF is designed using active inductors. A controllable current source is used to tune the BPF to select the bands of UWB range. The proposed RF front end is tuned to select the center frequencies 4, 5, 6.6, 7.96 and 10 GHz of UWB range. The obtained UWB bands are able to achieve a gain greater than 20 dB and a noise figure less than 5 dB. The designed RF front end consumed an average power of 23 mW.
