Description
Alpha鈥檚 two-stage balanced K band GaAs MMIC power
amplifier has a typical P
1 dB
of 24.5 dBm with 13 dB
associated gain and 11% power added efficiency at
23 GHz. The chip uses Alpha鈥檚 proven 0.25
碌m
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. A broad range of applications exist in both
the high reliability and commercial areas where high power
and gain are required.
