Description
Skyworks’ three-stage reactively-matched 24–30 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 Skyworks’ proven 0.25
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.
