Abstract :
A 90nm CMOS dual band power amplifier flip-chip module for 4G (WiMAX/LTE) applications with embedded process and temperature gain compensation circuit, is presented. The gain compensation circuit reduces the gain variation over temperature from 3dB/stage to 0.25dB/stage. Mask compliance is achieved at power (efficiency) of 26.7/26.3dBm (24/23%) and 27.9/27.3dBm (29/26%) for 10MHz WiMAX and LTE packets, at 2.5/3.5GHz bands, respectively.
