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
external variable voltage divider circuit. Typical RF performance at 10-GHz is: Insertion Loss 2-dB,
Maximum attenuation: 15-dB at 10 -GHz, input and output return loss: better than 10 -dB. DC block-
ing capacitors are provided on-chip.
The TGL8784-SCC is an absorptive attenuator designed using MESFET technology employing a “PI”
configuration which reduces bias currents and simplifies bias networks. 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
methods as well as thermocompression and thermosonic wire-bonding processes. The TGL8784-
SCC is supplied in chip form and is readily assembled using automated equipment. Groun d is
provided to the circuitry through vias to the backside metallization.
