Description
Skyworks' three-stage reactively-matched 2430 GHz MMIC low noise amplifier has typical small signal gain 17 dB with a typical noise figure at 28 GHz. The chip uses Skyworks' 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.
