Abstract :
A push-pull Class-AB CMOS PA is implemented using a broadband load-pull matching technique. The amplifier achieves a -3 dB bandwidth of 5.2 to 13 GHz with +25.2 dBm peak Psat and 21.6% peak PAE. The EVM for QPSK (4.5 MS/S) and 16 QAM (5 MS/s) are below 2.9% and 6.8% at 1 dB compression point. The measured BER for a wideband BPSK signal up to 7.5 Gb/s is less than 1013.
