Nonlinear modeling of class-E microwave power amplifiers

摘要

Verification of the Materka–Kacprzak model suitable for highly saturated MESFET operation is presented. To examine the validity of the model, a broadband microwave class-E power amplifier was designed and fabricated using a Siemens CLY5 MESFET transistor. A 200 MHz bandwidth (22%) from 0.82 to 1.02 GHz with a power-added efficiency greater than 60% was measured at an input power level of 15 dBm with a constant output power of 24 dBm.©1999 John Wiley & Sons, Inc.
