Abstract

Highly linear power amplifiers are key components of high capacity radio transmitters. This paper describes the complete procedure we established to develop a family of new MMIC power amplifiers aimed at achieving state-of-the-art performance as needed for a new M-QAM microwave radio. A cost effective approach dedicated to volume production has been addressed. The most important experimental characteristics for each of the developed MMIC PAs are also reported in order to demostrate the effectiveness of the presented procedure.
