This paper presents a 3.1~5.2 GHz ultra-wideband low noise amplifier (LNA) with a band-pass filter in the front of shunt feedback cascode topology fabricated in TSMC 0.18 μm CMOS process. More efforts are made on the wideband circuit and the choice of device in the high frequency. Consuming 27 mW from a 1.8 V power supply, simulation results show that S11 and S22 of circuit are lower than -14 dB, peak gain is 1.13 dB, flatness of gain is 15.92 dB and the noise figure of the LNA is from 1.84 dB to 2.11 dB over a full working band.
