Description
Alpha’s two-stage reactively-matched 37–40 GHz GaAs
MMIC driver amplifier has typical small signal gain of
13 dB with a typical P1 dB of 14 dBm at 38 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.
