A hybrid electronic/mechanical scanning array antenna including an outer housing and a cold plate rotatable therein. A waveguide aperture including an array of antenna elements is mounted to a top surface of the cold plate and a multi-layer circuit board is mounted to a bottom surface of the cold plate. A plurality of amplifier modules are mounted to the cold plate, where the circuit board includes a plurality of openings that allow the amplifier modules to be directly mounted to the cold plate, and the cold plate includes a plurality of RF signal channels that allow RF signals from the amplifier modules to travel through the cold plate. The amplifier modules are controlled to provide phase-weighting for electronic signal scanning in an elevation direction and rotation of the cold plate allows signal scanning in an azimuth direction.
