A Highly Efficient and nonLinear Class F Power Amplifier Design

Based on the portable systems application, it is necessary to design blocks with high efficiency to increasebattery lifetime. Power amplifier is the highest power consumption block in transmitter. The proposed circuit wassimulated using ADS Agilent based on 0.18 μmμm TSMC RF CMOS technology and supply voltage of 3.3V ontransistor level. The proposed power amplifier was designed by Class F type at 900 MHz with 60% efficiency andoutput powers of 27 dBm.
