Abstract
An apparatus is provided. A plurality of transceiver antennas are arranged to form a phased array, where each antenna include a differential transmit antenna and a differential receive antenna arranged in a first pattern. A plurality of transceivers are arranged in a second pattern that is substantially symmetrical, and each transceiver is associated with at least one of the transceiver antennas and includes a feed network. Each feed network has a power amplifier (PA), a first matching network that is coupled between the PA and its associated transmit antenna so as to translate the phase of each differential transmit signal, a low noise amplifier (LNA), and a second matching network that is coupled between the LNA and its associated receive antenna so as to translate the phase of each differential receive signal.
