The TriQuint TGA8310 - SCC is a monolithic low - noise distributed amplifier, which operates
from 2 to 20- GHz. Noise figure is typically 4 - dB. Nine 122 - µm gatewidth FETs typically provide
17.5- dBm of output power at 1 - dB gain compression and 9 - dB typical small signal gain. Typical input
return loss is 17- dB from 2 to 20 - GHz. Typical output return loss is 20- dB. Ground is provided to
the circuitry through vias to the backside metallization.
The TGA8310 - SCC low - noise distributed amplifier is suitable for a variety of wide - band electr onic
warfare systems such as radar warning receivers, electronic counter-measures, 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 ther mocompression and ther mosonic wir e - bonding processes. The
TGA8310 - SCC is supplied in chip form and is readily assembled using automated equipment.

Ratings over operating channel temperature range, T

(unless otherwise noted)
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated under "RF Characteristics" is not implied. Exposure to absolute maximum rated conditions for
extended periods may af fect device reliability.
* For operation above 25 C base - plate temperature, derate linearly at the rate of 5.5 mW/ C.
** Operating channel temperatur e directly affects the device MTTF . For maximum life, it is recommended that
channel temperature be maintained at the lowest possible level.
