摘要

An apparatus includes a phased array antenna panel and one or more beam former circuits mounted on the phased antenna array panel. The phased array antenna panel generally comprises a plurality of antenna elements arranged in one or more groups. Each of the one or more beam former circuits may be coupled to a respective group of the antenna elements. Each of the one or more beam former circuits may comprise a plurality of transceiver channels. Each transceiver channel generally comprises a power amplifier circuit configured, when operating in a transmit mode, to drive a respective one of the antenna elements. The power amplifier generally comprises a feedback network coupled between an output and an input of the power amplifier circuit.
