ABSTRACT:
A RF power amplifier with the advantages of high output efficiency and a wide range of gain control is disclosed. By appropriately biasing the power transistor of the power-stage amplifier in the RF power amplifier, the power-stage amplifier functions as a class C amplifier. By varying the bias source of the driving-stage amplifier and keeping the bias sources of the input-stage and power-stage amplifiers at a fixed level, the driving-stage can output a driving signal with a wide range of variable gain. Consequently, the driving signal can be used to drive the power-stage amplifier to obtain highly efficient output and of a wide range of output power gain control.
