Abstract
This paper presents a high-efficiency power amplifier based on a harmonic control matching network. We proposed a harmonic control matching network based on a Chebyshev filter that can match the load to the optimum power matching impedance at fundamental and harmonic frequencies as well as block harmonic signals. The power amplifier applied to the proposed harmonic control matching network has high efficiency and excellent harmonic suppression performance without an additional low-pass filter. The fabrication and measurements were conducted to verify the proposed circuit. The implemented power amplifier achieved 61.3~76.3% drain efficiency in the frequency band of 2.8~3.2 GHz, and it was shown that a second harmonic suppression of under −46 dBc was achieved.
