Abstract
An apparatus includes a phased array antenna panel and one or more dual-polarization beam former circuits mounted on the phased array antenna panel. The phased array antenna panel generally comprises a plurality of dual-polarization antenna elements. The plurality of dual-polarization antenna elements are generally arranged in one or more groups. Each dual-polarization beam former circuit may be coupled to a respective group of the dual-polarization antenna elements. Each dual-polarization beam former circuit generally comprises a plurality of transceiver channels. Each transceiver channel generally comprises a horizontal channel and a vertical channel. Each dual-polarization beam former circuit provides polarization rotation through bias current control in each of the vertical and horizontal channels.
