Paper Abstract

A set of HEMT MMICs including LNAs and phase shifters has been developed for an all-HEMT 20 GHz phased array receiver applications. These MMICs use state-of-the-art HEMT devices for low noise figure, innovative design techniques for compactness, and proven wafer processing for high yield. The LNA achieved a noise figure of 2.5 dB with an associated gain of 22 dB. The 3-bit phase shifter achieved 6 to 7.8 dB insertion loss for all states. With their performance and high process yield, these MMIC chips can be inserted into a system to demonstrate the next generation phased array performance.
