The TriQuint TGA8349 -SCC is a GaAs monolithic low -noise distributed amplifier designed
for use as a multi -octave general-purpose gain block. Nine 122 -µm gate width FETs provide 11-dB
nominal gain and 3.1- dB noise figure from DC to 14 -GHz. Typical power output is 16 -dBm at
1-dB gain compression. Typical input SWR is 1.2:1 and output SWR is 1.3:1. Gr ound is provided to
the circuitry through vias to the backside metallization.The DC to 14 -GHz frequency range, dual -gate
AGC control and gain-flatness characteristics make the TGA8349 -SCC suitable for many system
applications including fiber optic.
The TGA8349-SCC is supplied in chip for m and is engineer ed for high -volume automated assembly.
All metal sur faces are gold plated to be compatible with ther mocompression and thermosonic
