A 2.62-GHz class-F power amplifier with lumped-element and transmission line network design

A 2.62-GHz class-F power amplifier with independent analogous method, lumped-element network design is presented. The amplifier is designed using CGH40010 GaN HEMT transistor device with 5 th order low pass structure at the lumped-element output network. A transmission line networks has been used in transformation of both input and output of the amplifier. Optimum fundamental impedance matching networks and optimization are applied at the frequencies of interest to controlling the even and odd harmonics, to allow fundamental frequency deliver to the load. The power amplifier achieves 81.5% peak efficiency at 18.1dBm output power.
