Abstract

This paper describes a novel power amplifier based on Enhancement mode PHEMT (E-PEHMT) suitable for low cost 7-18 GHz applications. The designed power amplifier exhibits 20 dB of small signal gain, 30dBm P-1dB output power at 17 GHz. A 50 Ω output match and single 5V supply requirement simplify the application. These MMIC is fabricated in Agilent’s advanced E-PHEMT 0.25u gate process and packaged in a 5x5mm surface mount laminate package for ease in assembly. This is the only known or published E-PHEMT MMIC power amplifier to work at these frequencies for SMT applications.
