Abstract:

This paper describes the design of a Gilbert mixer based channel to channel gain and phase mismatch calibration loop for 5G 4 channels 24:30 GHz beamformers. The input dynamic range of the loop is 14dB centered around the 5G beamformer channel average output power (SdBm) and the simulation results shows that the calibration accuracy is +/-0.25 dB of gain variation and +/-2.5 degrees of phase variations between all channels. The proposed Gilbert cell calibration loop is designed in TSMC 65nm technology with static power consumption of 4 m Watts from 3.3V supply.
