The solution employs a five\u2010transistors architecture in the switch, with the objective of reducing loss and chip size. The polar class\u2010G architecture enables differential amplification, thus ensuring a stable signal output and a notable enhancement in overall efficiency. The matching network adopts a transformer which employs a differential\u2010to\u2010differential signal input methodology to enhance signal integrity and circumvent signal distortion. The proposed class\u2010G SCPA is implemented in a 65\u2009nm CMOS process at 2.4\u2009GHz, with a peak output power of 25.09\u2009dBm, a peak power\u2010added efficiency (\n) of 38.47%, and a \n of 29.8% under a 6\u2010dB backoff condition.
