Abstract

This paper discusses the effects of combining structures on the RF and thermal performance of LDMOS high power amplifiers under mismatch conditions. Using a high gamma tuner, a typical power amplifier module is measured in terms of power and temperature in mismatch. Based on these measurements, the advantages and disadvantages of in-phase and balanced combining topologies are shown in the context of industrial applications.
