Description
The TriQuint TGA8334-SCC is a GaAs monolithic dual-gate distributed amplifier.
Small-signal gain is typically 8 dB with positive gain slope across the band. Input
and output return loss is typically greater than 9.7 dB. Five 600um gatewidth FETs
provide more than 26 dB output power at 1 dB gain compression at midband.
Ground is provided to the circuitry through vias to the backside metallization.
The TGA8334-SCC is directly cascadable with other broadband TriQuint GaAs
amplifiers, such as the TGA8300-SCC, TGA8622-SCC, and TGA8220-SCC. This
general power amplifier is suitable for a variety or wide-band applications such as
distributed networks, logging stages and oscillator buffers.
Bond pad and backside metallization is gold plated for compatibility with eutectic
alloy attachment methods as well as the thermocompression and thermosonic wire
bonding processes. The TGA8334-SCC is supplied in chip form and is readily
assembled using automated equipment.
