Description
Alpha’s two-stage balanced K band GaAs MMIC power
amplifier has a typical P_{1 dB} of 22 dBm with 13 dB
associated gain guaranteed across frequency range
21–23 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 small signal S-parameters and power
characteristics prior to shipment for guaranteed
performance.
