600W rf power amplifier

  

Posted on Oct 31, 2012    4354

A unique push-pull parallel circuit. It uses four MRF150 RF power FETs paralleled at relatively high power levels. Supply voltages of 40 to 50 Vdc can be used, depending on linearity requirements

The bias for each device is independently adjustable; therefore, no matching is required for the gate threshold voltages.
