Power synthesis of class E tuned power amplifier

The merge of the output power of class E amplifiers with the power synthesizer was used as the source of power of the RF emission machine with high efficiency and power. The operation behavior of class E amplifier and the isolation and synthetic characteristics of the same phase power synthetic network are analyzed in the paper. Under the optimum operation condition, the waveforms of the collector current and collector-emitter voltage, and the values of the load-network components are determined. A kilowatt-level synthetic circuit applying the same phase power is given, which provides a reference basis for the design of the RF emission machine.
