摘要

An apparatus includes a plurality of transceiver circuits and a plurality of feedback networks. Each of the plurality of transceiver circuits may be coupled to a respective antenna element in a respective group of antenna elements of a phased array antenna. Each of the transceiver circuits generally comprises a power amplifier circuit configured, when operating in a transmit mode, to drive the respective antenna element in the respective group of antenna elements. Each of the plurality of feedback networks may be coupled between an output and an input of a respective power amplifier circuit of a respective transceiver circuit. Each of the feedback networks generally comprises a resistor and a capacitor connected in series. The respective power amplifier circuit with the feedback network generally maintains a power matching condition with load variation associated with the antenna elements of the phased array antenna.
