Low Noise Amplifier, AGC
The TriQuint TGA1342-SCC is a monolithic dual gate low noise distributed amplifier with AGC via the control gate. This low noise amplifier (LNA) operates from 2 to 20 GHz. Nine 120 um gatewidth FETs typically provide 3.5 dB of noise figure, 17.5 dBm of output power at 1 dB gain compression and 9 dB small signal gain. Typical input return loss and output return loss are 20 dB. Ground is provided to the circuitry through vias to the backside metallization.
The TGA1342-SCC low noise distributed amplifier is suitable for a commercial radio and a variety of wideband electronic warfare systems such as radar warning receivers, electronic countermeasures, decoys, jammers and phased array systems.
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 TGA1342-SCC is supplied in chip form and is assembled using automated equipment.
