High-efficiency linear RF Amplifier - a unified circuit approach to achieving compactness and low distortion

The realization of a highly efficient linearized amplifier has emerged as a paramount issue in the design of advanced mobile handsets. In this paper, a new RF amplifier linearization scheme using a compensating transistor combination is proposed. The devised approach ably utilizes all terminals of a...
