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 volt 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 blocking capacitors are
provided on-chip.
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 compatibility with eutectic
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. Ground is provided to the circuitry through vias the
backside metallization.
