ABSTRACT:
A modular amplifier comprising a plurality of modules receives a signal to be amplified and provides an amplified signal through power divider and power combiner circuits which are mirror images of each other. In particular, 2-way Wilkinson hybrid circuits are combined to deliver the input signal by providing a divided signal to each of the amplifier modules. The output of each of the modules is combined by 2-way Wilkinson hybrid circuits to provide the amplified signal output. In order to provide discrete power reduction switching from a full power condition to a reduced power condition, at least one of the inputs to a module is connected to a quarter-wave stub which is selectively grounded and open-circuited to reflect respectively an open circuit and a short circuit condition. In this way, each amplifier module performs similarly in the reduced power output condition as well as in the full power output condition.
