This paper presents a highly efficient class-B power amplifier at 2.4 GHz. Efficiency enhancement is achieved by terminating the input and output of the amplifier with its optimum source and load ...

This work presents a Class F -1 power amplifier (PA) operating at 2.35 GHz. An output power of 40 W (46 dBm) was achieved with 10 dB gain. The maximum drain efficiency was measured to be 60.8% (PAE = ...
