Abstract
An apparatus includes a plurality of transmitter channels and a plurality of feedback networks. Each of the plurality of transmitter channels may be coupled to a respective antenna element in a respective group of antenna elements of a phased array antenna. Each of the transmitter channels generally comprises a power amplifier circuit configured to drive the respective antenna element in the respective group of antenna elements to produce and steer a radio-frequency beam. 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 transmitter channel. 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 performing beam steering of the radio-frequency beam using the antenna elements of the phased array antenna.
