Abstract

A 32-GHz, 21-element array feed incorporating 63 MMIC (monolithic microwave integrated circuit) devices and providing electronic beam steering using 21 VLSI control chips is under development. An innovative building-block construction approach providing easy verification of device performance prior to integration in the array is described. In addition, the subarray layer concept with plug-in RF connectors allows for easy removal of a layer for repairing one of the components. This planar array demonstrates state-of-the-art design technology required for implementation of Ka-band transmit arrays in future NASA (US National Aeronautics and Space Administration) deep-space missions.<>
