摘要

The DARPA Millimeter Wave Digital Arrays (MIDAS) program is demonstrating the first element level digital millimeter wave phased arrays covering the 18-50 GHz band. The performers are leveraging compound semiconductors, CMOS and heterogeneous integration to meet the stringent size and power constraints while pushing the state-of-the-art in RF and mixed-signal design. The 4×4 element dual-polarized transceiver tile will be a building block to enable scalable arrays mobile-to-mobile ad-hoc networking and emerging proliferated low-earth orbit (LEO) satcom. Element-level digital beamforming has the potential to enable multi-beam operation for reduced network discovery time and increased network throughput.
