✦ Synopsis

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 poweradded efficiency greater than 60% was measured at an input power level of 15 dBm with a constant output power of 24 dBm.
