Features
Excellent Linear Output Amplifier Stage 19.0 dB Small Signal Gain +30.0 dBm P1dB Compression Point +39.0 dBm Third Order Intercept (OIP3) 100% On-Wafer RF, DC and Output Power Testing 100% Visual Inspection to MIL-STD-883 Method 2010
Mimix Broadband’s two stage 21.0-24.0 GHz GaAs MMIC power amplifier is optimized for linear operation with a third order intercept point of +39.0 dBm. This MMIC uses Mimix Broadband’s 0.15 µm GaAs PHEMT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity. The chip has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy www.DataSheet4U.comor eutectic solder die attach process. This device is well suited for Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
