Distributed power amplifier with active matching

摘要

A distributed power amplifier arranged to operate over a bandwidth. An input side with an input terminal is arranged to receive an input signal and connected to an input transmission line. An output side with an output terminal is adapted to deliver an output signal and connected to an output transmission line. A power splitter is connected to the input terminal, thus being arranged to divide the input signal in a first path to the input transmission line and in a second path to an input of an active matching circuit. The active matching circuit has an output connected to the output transmission line. The other end of the output transmission line is connected to the output terminal. A method to design a distributed power amplifier and to modify existing distributed power amplifiers.
