Abstract
A composite amplifier comprises several Chireix pairs (PA11, PA12; PA21, PA22) of power amplifiers connected to a common load. Means (21) are provided for driving each Chireix pair by drive signals having amplitude dependent phase over at least a part of the dynamic range of the composite amplifier . These parts are preferably different for different pairs.
