Abstract :
A CMOS class-F power amplifier was developed based on the second and third harmonic control output network for WiMAX application. The harmonic control network was implemented on an off-chip PCB. The measured power performance are more than 24.4% with P1dB = 20.2 dBm and Gp = 13.1 dB at a low drain voltage of 1.8 V. The ACPR was below -33 dBc under standard WiMAX modulated signal at 5 dBm input power.
