Description

The TriQuint TGA8344-SCC features two cascaded monolithic low-noise distributed amplifiers with on-chip bias operating from 2 to 18 GHz. This die offers the advantage of high gain, typically 19 dB, in compact die size with simplified biasing configuration. Noise figure is typically 4 dB. The two cascade amplifiers have eighteen 122 um gatewidth FETs providing 16 dBm of output power at 1 dB gain compression. Input return loss is typically 14 dB from 2 to 18 GHz and output return loss is typically 13 dB. Ground is provided to the circuitry through vias to the backside metallization. The TGA8344-SCC small size and high gain make it suitable for use in a variety of wide-band electronic commercial and warfare systems.
