Researchers develop first silicon wafer-scale 110 GHz phased array transmitter

(PhysOrg.com) -- TowerJazz, the global specialty foundry leader, and The University of California, San Diego, provider of a leading program in microwave, millimeter-wave and mixed-signal RFICs, today announced they have demonstrated the first wafer-scale phased array with 16 different antenna elements operating at 110 GHz frequency range.  First time success was achieved for the RFIC using TowerJazz’s own proprietary models, kit and the mmWave capabilities of its 0.18-micron SiGe BiCMOS process, SBC18H3.   The device targets applications for automotive radar, aerospace and defense, passive imaging, security, and mmWave imaging. The collaboration of the phased array chip was partly funded by DARPA.
