Description
Alpha’s three-stage reactively-matched 25–29 GHz
GaAs MMIC driver amplifier has typical small signal gain
of 17 dB with a typical P
1 dB
of 16 dBm at 26.5 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.
