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.

All bias r esistors have a nominal value of 25 - Ohms.
RF connections: Bond using two 1-mil diameter , 20 to 25-mil- length gold bond wires at both RF Input and
RF Output for optimum RF per formance.
DC blocks are not provided at RF ports.
Close placement of external components is essential to resonant-free performance.
