RF pre-amplifiers and power amplifiers

An RF amplifier circuit includes a MOSFET connected to an RF output of the circuit via an impedance matching network including an inductor and a tuning capacitor connected in parallel with the inductor and the MOSFET. DC voltage is applied to the MOSFET via a series path through a radio frequency ch...
