Abstract :
20 GHz low-noise and 44 GHz power MMIC amplifiers have been developed that could improve the manufacturability and cost of MILSTAR EHF phased array communication antennas. The six-stage power amplifier has 32.7 dB gain with 16.7 dBm output power and 17% power added efficiency. The chip measures 1.79 mm/sup 2/ and operates off two supplies. The four-stage LNA demonstrates 26 dB gain with 2.2 dB noise figure and 15 dB return loss. The LNA chip measures 1.18 mm/sup 2/ and operates off a single supply.<>
