Description
Alpha’s two-stage reactively-matched 27–31 GHz GaAs
MMIC driver amplifier has typical small signal gain of
14 dB with a typical P1 dB of 16 dBm at 28 GHz. The chip
uses Alpha’s proven 0.25 µm 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 27–31 GHz LMDS and digital
radio bands.
