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. 0.087 0.124 2.710 2.600 2.146 1.813 1.264 0.000 0.246 100% Visual Inspection to MIL-STD-883 MT 2010 0.588 0.000 100% On-Wafer RF, DC and Noise Figure Testing Dimensions indicated in mm.
