  Alpha's three-stage reactively-matched 27-31 G GaAs MMIC driver amplifier AA028P3-00 has typical small signal gain of 19 dB with a typical P_{1 dB} of 16 dBm at 28 GHz.The chip uses Alpha's proven 0.25m MESFET technology, and is based upon MBE layers and electron beam lithography for the highest uniformity and repeatability.

  The FETs employ surface passivation to ensure a rugged, reliable part with through-substrate via holes and gold-based backside metallization to facilitate a conductive epoxy die attach process.All chips are screened for gain, output power and S-parameters prior to shipment for guaranteed performance.Designed for 27¨C31 GHz LMDS and digital radio bands.
