Wafer-Scale Millimeter-Wave Phased-Array RFICs

Presents a summary of the millimeter-wave wafer-scale phased array work at UCSD. This concept can drastically reduce the cost of millimeter-wave phased arrays by combining the RFIC blocks, antennas, power distribution and summing, digital control and up and down converters all on the same wafer (or large piece of silicon), and eliminates all RF transitions in and out of the chip, therefore resulting in more efficient systems and lower cost systems. Examples at 90-100 GHz, 108-114 GHz and 400 GHz will be presented in this paper, together with their measured antenna patterns.
