A new digital lookup table adaptive pre-distortion technique for power amplifier linearization is presented. This approach uses a multi-port receiver at linearization loop in place of a classic heterodyne receiver. The five-port receiver is implemented by use of the passive microwave circuits and detector diodes. The system is designed to satisfy 3G power amplifier specifications. The performance...
