In this letter, a high-efficiency filter-integrated class-F power amplifier (PA) is presented. High-Q-factor dielectric resonator (DR) filter is employed as the output matching network of the class-F ...

The operation of a single ended CMOS class E power amplifier imposes voltage stresses on the drain terminal of the switching transistor that preclude the use of large bias drain voltages. On this ...
