Integrated microwave modular transceiver tile structure in the form of a cube-like configuration, and including (a) a first, generally planar, circuit-board layer structure possessing an array of plural, integrally formed microwave transceivers arranged in a defined row-and-column pattern, with each transceiver having an associated transceiver axis extending generally normal to the plane of said the first layer structure, and (b) a second, generally planar, circuit-board layer structure including transceiver-function operational circuitry operatively connected to the transceivers, and functional to promote operation of the transceivers simultaneously in transmission and reception modes of operation.
