Abstract: A vector-summing phase shifter (VSPS) with gm-boosted structure followed by a variable gain amplifier (VGA) with low phase variation, i.e., PS-VGA, was demonstrated at 27–31 GHz.

Abstract: This paper presents a Q-band ultralow-power pseudomorphit high electron mobility transistor (pHEMT) low noise amplifier (LNA) MMIC. A novel low power technology has been proposed to decrease ...
