Abstract
An RF power circuit comprises a power transistor having a gate and drain, an output matching network coupled to the drain and an input matching network coupled to the gate. A closed-loop bias circuit is integrated with the power transistor on the same die and coupled to the gate for biasing the RF power transistor based on a reference voltage applied to the bias circuit.
