DESCRIPTION
The TriQuint TGL6425-SCC is a GaAs MMIC 5- bit FET attenuator which operates fr om
0.5 to 18-GHz. The attenuation step is 0.5- dB and is controlled by 10 input lines. Control bias voltages
are 0 V and -5 V. The input and output return loss is typically 13 - dB.
This unique absorptive design combines both “T”and “PI”configurations to produce an extremely
small size and low inser tion loss attenuator. The small size and reliability advantage of a monolithic
attenuator over a hybrid design make this device attractive for use in electronic war fare, radar,
telecommunication, and navigation systems for level set, modulation and switching functions.
Bond pad and backside metallization is gold plated for compatibility with eutectic alloy attachment
method as well as the thermocompression and thermosonic wire bonding processes. Ground is
provided to the circuitry through vias to the backside metallization.

Ratings over operating channel temperature range, TCH (unless otherwise noted)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are str ess 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.
*Operating channel temperature, TCH, will directly affect the device MTTF . For maximum life, it is recommended
that channel temperature be maintained at the lowest possible level.
