Analysis on the Balanced Class-E Power Amplifier for the Load Mismatch Condition★
نویسندگان
چکیده
Analysis and simulation are presented of the mismatched load condition for a balanced class-E power amplifier, which is based on 90° hybrids at its input and output. The performances of the 200-Watt balanced class-E amplifier, such as the output power and efficiency, were analyzed and compared to the conventional single-ended class-E power amplifier for the 1:3 VSWR mismatch condition. The simulated results showed that the balanced class-E power amplifier has a standard deviation of 0.7 dB at an average output power of 51 dBm for complete 1:3 VSWR deviation, while the single-ended amplifier has a standard deviation of 2.4 dB at the same output power. For power-added efficiency, the balanced amplifier has a much lower standard deviation of 1.9 % compared to the single-ended amplifier which has 10.9 % at the same condition.

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
