Description
Alpha's four-stage reactively-matched 28-40 GHz GaAs MMIC low noise amplifier has typical small signal gain of 17 dB with a typical noise figure of 3.8 dB at 38 GHz. The chip uses Alpha's 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.
