Description
Alpha’s two-stage balanced 28–36 GHz MMIC low noise
amplifier has typical small signal gain of 12 dB with a
typical noise figure of 2.6 dB at 32 GHz. The chip uses
Alpha’s proven 0.25
µm
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.
