This paper presents a 5G wireless receiver front-end for 3.3GHz – 3.8GHz licensed band application. The front-end is designed in 0.35um BiCMOS process. Simulation results show the low-noise amplifier’s power gain is 23.1dB, noise figure is 2.5dB and input return loss is lower than -20.7dB. The conversion gain of the mixer is 13.2dB, max LO input power is -3dBm and the 3rd-order input intercept point is -8dBm. The tuning range of the voltage controlled oscillator is from 3.48GHz-3.72GHz; and phase noise is all below -109.4dBc/Hz. Total power consumption of this 5G front-end is 54.9mW including all buffers.
