A mode-transferring technique for designing high-frequency high-efficiency broadband power amplifiers is presented in this paper. It is demonstrated, for the first time, that by properly tuning the second and third harmonic impedances, a PA can operate between inverse Class-F and Class-F modes within a 1.5 ∶ 1 bandwidth. A broadband PA is designed by employing this technique with a commercial GaN transistor. The multi-mode PA operation and broadband matching are realized simultaneously using a… CONTINUE READING
