L-Band LDMOS Power Amplifiers Based on an Inverse Class-F Architecture
Journal article, 2005

Two inverse Class F power amplifiers working at 1 GHz and 1.8 GHz respectively have been developed. The PAs use a LDMOS transistor as an active element in order to generated high efficiency with high output power. The 1 GHz PA achieved a drain efficiency of 77.8 % with 12.4 W of output power and the 1.8 GHz PA a drain efficiency of 60 % with 13 W of output power. To our knowledge these results represent the highest efficiency and output power for an inverse Class F PA based on a single LDMOS transistor working at these frequencies.
