Abstract:
One embodiment is directed to a system that comprises a non-DPD RF transceiver circuit that does not include digital pre-distortion (DPD) functionality and a DPD RF transceiver integrated circuit that includes DPD functionality. A first analog RF transmit signal output by the non-DPD RF transceiver circuit is received by a receive signal path of the DPD RF transceiver integrated circuit so that receive baseband data generated by the receive signal path is indicative of the first analog RF transmit signal. The receive baseband data generated by the DPD RF transceiver integrated circuit is received by a transmit signal path of the DPD RF transceiver integrated circuit. A second analog RF transmit signal output by the transmit signal path is a digitally pre-distorted version of the first analog RF transmit signal for amplification by the power amplifier.
