Product Data Sheet Discrete MESFET TGF1350-SCC Key Features and Performance • • • • • 0.5 um x 300 um FET 1.5 dB Noise Figure with 11dB Associated Gain at 10 GHz 2.5 dB Noise Figure with 7 dB Associated Gain at 18 GHz All-gold Metallization for High Reliability Recessed Gate Structure Description The TriQuint TGF1350-SCC is a single-gate GaAs field-effect transistor (FET) used for low-noise applications DC to 18 GHz. Bond pad is gold plated for compatibility with thermocompression and thermosonic compatibility wire-bonding processes. The TGF1350-SCC is readily assembled using automated equipment. Die attach should be accomplished with conductive epoxy only. Eutectic attach is not recommended .
