Abstract
There is provided a modular amplifier structure that includes a plurality of parallel amplifier sub-units. Each amplifier sub-unit is configured to amplify a received payload signal under control of at least one received control signal. Outputs of the amplifier sub-units are applied to a combining circuit. The combining circuit is configured to combine the outputs of the plurality of amplifier sub-units to provide an amplified payload signal.
