Adaptive Gain and Phase Adjustment for local linearization of Power Amplifiers of micro/mm-wave Phase arrays
A wideband, local Power Amplifier (PA) linearization technique is presented. The proposed Adaptive Gain and Phase Adjustment (AGPA) local linearization technique compensates for both AM-AM and AM-PM distortion of PA for large channel bandwidths of hundreds of megahertz. A 60GHz PA designed in a 28nm CMOS process is designed and measured. AGPA improves the OP1dB of the stacked PA by 2.8dB from 9.5dBm to 12.3dBm and reduces the IM3 products by 3dB with a tone spacing of 200MHz at 8dBm output power.
