Abstract: Switch-mode amplifiers have gained interest in the RF-frequency range, due to their promising features of high linearity and especially high efficiency, compared to conventional class-AB ...

and an adaptive controlled gate bias circuit is constructed and the control shape is optimized experimentally. The performance of the microwave Doherty amplifier is compared with that of a class AB ...
