Skyworks' three-stage balanced K band GaAs MMIC power amplifier has a typical of 24 dBm and a typical PSAT of 26 dBm at 26.5 GHz. The chip uses Skyworks' proven 0.25 µm MESFET 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. All chips are screened for small signal S-parameters and power characteristics prior to shipment for guaranteed performance. A broad range of applications exist in both the commercial and military areas where high power and gain are required.
