A Novel Low Cost Enhancement Mode Power AmplifierudMMIC in SMT Package for 7 to 18 GHz Applications

摘要

This paper describes a novel powerudamplifier based on Enhancement mode PHEMTud(E-PEHMT) suitable for low cost 7-18 GHzudapplications. The designed power amplifierudexhibits 20 dB of small signal gain, 30dBm P-1dBudoutput power at 17 GHz. A 50 Ω output matchudand single 5V supply requirement simplify theudapplication. These MMIC is fabricated inudAgilent’s advanced E-PHEMT 0.25u gate processudand packaged in a 5x5mm surface mountudlaminate package for ease in assembly. This is theudonly known or published E-PHEMT MMICudpower amplifier to work at these frequencies forudSMT applications.
