Zusammenfassung:An apparatus includes a phased array antenna panel and one or more beam former circuits mounted on the phased array antenna panel. The phased array antenna panel generally comprises a plurality of antenna elements. The plurality of antenna elements are generally arranged in one or more groups. Each beam former circuit may be coupled to a respective group of the antenna elements. Each beam former circuit generally comprises 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 circuit generally comprises separate bias and voltage supply inputs providing additional power control.
