Description
Alpha鈥檚 three-stage reactively-matched 24鈥?0 GHz
MMIC low noise amplifier has typical small signal gain of
17 dB with a typical noise figure of 3.0 dB at 28 GHz.
The chip uses Alpha鈥檚 proven 0.25
碌m
low noise PHEMT
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.
Dimensions indicated in mm.
All DC (V) pads are 0.1 x 0.1 mm and RF In, Out pads are 0.07 mm wide.
Chip thickness = 0.1 mm.
