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 de vice at these or any other conditions beyond those indicated under "RF Characteristics" is not implied. E xposure to absolute maximum rated conditions for extended periods may affect device reliability.
* Operating channel temperature directly affects the de vice MTTF. For maximum life, it is recommended that channel temperature be maintained at the low est possible level.

Description

The TriQuint TGL8784-SCC is a monolithic variable attenuator which operates from 2 to 20 -GHz. This analog attenuator can operate from a single +2.5 v olt power supply if used with an xternal variable voltage divider circuit. Typical RF performance at 10 -GHz is: Insertion Loss 2-dB, aximum attenuation: 15 -dB at 10 -GHz, input and output return loss: better than 10 -dB. DC blocking capacitors are provided on-chip.

The TGL8784-SCC is an absorptive attenuator designed using MESFET technolog y employing a "PI" onfiguration which reduces bias cur rents and simplifies bias networ ks. The broadband capabilities of this device are versatile in many applications such as telecommunications, military, and space. This device has a space heritage.

Bond pad and backside metallization is gold plated for compa tibility with eutectic alloy attachment ethods as well as thermocompression and thermosonic wire-bonding processes. The TGL8784 - SCC is supplied in chip for m and is readily assembled using automated equipment. Groun d is provided to the circuitr y through vias to the backside metallization.
