Abstract: An integrated fully differential ultra-wideband CMOS RF front-end for 69 GHz is presented. A resistive feedback low noise amplifier and a gain controllable IQ merged folded quadrature mixer are integrated as the RF front-end. The ESD protected chip is fabricated in a TSMC 0.13 μm RF CMOS process and achieves a maximum voltage gain of 2326 dB and a minimum voltage gain of 1619 dB, an averaged total noise figure of 3.34.6 dB while operating in the high gain mode and an in-band IIP3 of 12.6 dBm while in the low gain mode. This RF front-end consumes 17 mA from a 1.2 V supply voltage.

Key words: CMOS, Ultra-wideband (UWB), resistive feedback low noise amplifier (LNA), folded quadrature mixer, noise figure, linearity
