This paper presents, for the first time, a MEMS-enabled dual-band receiver front-end in 0.13-mum CMOS, which covers both 1.8-GHz and 5-6-GHz bands. A packaged MEMS series switch is used to tune the LNA's input impedance for narrow-band matching in each of these bands. The mixer of the front-end is a double-balanced folded Gilbert cell, which is followed by a programmable current-output stage. The front-end shows a measured gain of 45 dB and a NF of 4.2 dB at 1.85 GHz. The LNA's IIP3 is -9 dBm at 1.85 GHz. The front-end consumes 28 mA from a 1.2-V power supply
