Abstract
A plurality of FET or other amplifiers are connected between respective outputs of an N output port power divider network and respective inputs of an N input power combining network in a variable power amplifier system. A gate bias is selectively supplied to each of the amplifiers which is either at a first value to cause the amplifier to amplify or at a second value to cause the amplifier to be cut off and therefore to not dissipate any DC power. The number of amplifiers receiving the first potential is determinative of the amount of power amplification of the variable power amplifier.
