## Abstract This paper presents a compact Xβband, 9 W AlGaAs/InGaAs/GaAs PHEMT MMIC high power amplifier. This amplifier is designed to fully match a 50 Ξ© input and output impedance. Based on 0.35 ΞΌm gateβlength power PHEMT technology, a twoβstage power amplifier is fabricated on a 3βmil thick wafe
## Abstract This article presents the design, measurement, and test of a MMIC for the frontβend section of a composite multielement radiating system. The MMIC is composed of a 3βBIT modified constant phase digital attenuator, a switch, and a pair of amplifiers for TX/RX operation. A uniform linear
