Abstract

A wireless transceiver using a phased array antenna panel for producing multiple beams includes receive antennas forming a receive configuration and transmit antennas forming a transmit configuration. The receive antennas form a plurality of receive beams and the transmit antennas form a plurality of transmits beams, based on phase and amplitude information provided by a master chip in the phased array antenna panel. The receive and transmit configurations can include sub-configurations, each sub-configuration forming one of the plurality of receive beams or one of the plurality of transmit beams. At least one receive antenna and at least one transmit antenna can be connected to a corresponding plurality of receive phase shifters and a corresponding plurality of transmit phase shifters respectively. The wireless transceiver can form a relay transmit beam based on a receive beam provided by a hardwire connection.
