Millimeter Wave Digital Arrays (MIDAS) TA2: Millimeter-Wave Scalable Unconstrained Broadband Arrays (MMW SCUBA)

The Millimeter-Wave Scalable Unconstrained Broadband Array (MMW SCUBA) system leverages cutting edge chip integration, additive manufacturing, and packaging technology to realize an 18–50 GHz, dual-polarized, scalable phased array antenna with element-level digital beamforming. We report on the demonstration and test of a 16 element free-space-to-RF prototype, as well as progress on the development of a larger 64 element array prototype build which extends integration from free-space to digits.
