During the past 50 years, phased-arrays have been largely developed for the defense sector. Today, due to the increased demand for data, there is a need for base-station and mobile-user phased-arrays which can provide high-capacity data services through directional links. Both digital-beamforming at the element level (sub-6 GHz) and hybrid (i.e. analog/digital) beamforming for the mm-waves bands are being developed for 5G systems. These commercial investments are leading to dramatic changes in phased-arrays: High-EIRP high-performance systems at 12, 14 GHz and 28 GHz (SATCOM), X/Ku-band (Radars), 24-30 GHz, 37-42 GHz and even 60 GHz (all for 5G), and with multiple beams, are now available at low cost. The single most important aspect of these arrays is their use of advanced silicon technologies and planar antennas for dramatically lowering the development and unit cost. Also, a new way of doing complete BIST (built-in-self-test) is lowering the cost of phased-array testing. Still, it is important to test phased-arrays for OOBE (out of band emissions, LO leakage), EVM (error vector magnitude), cross-pol and sidelobe conformance (especially for SATCOM), and 2x2 and 4xx4 MIMO links (for 5G). The talk will summarize the work in this area from defense to commercial applications and review the performance verification test challenges of these devices, including EMC implications. A roadmap for the future to further lowering the cost of phased-arrays will conclude the talk.
Prof. Gabriel M. Rebeiz is Member of the National Academy, Distinguished Professor and the Wireless Communications Industry Endowed Chair at the University of California, San Diego. He is an IEEE Fellow, and is the recipient of the IEEE Daniel E. Nobel Medal, the IEEE Microwave Theory and Techniques (MTT) Microwave Prize (2000 and 2014), the IEEE MTT 2010 Distinguished Educator Award and the IEEE Antennas and Propagation 2011 John D. Kraus Antenna Award. His group has lead the development of complex RFICs for phased array applications from X-band to W-band, culminating recently in wafer-scale integration with high-efficiency on-chip antennas. His phased array work is now used by most companies developing complex communication and radar systems. He has graduated nearly 100 PhD students and post-doctoral fellows.
