CHT4016-QEG
4-14GHz 6-bit digital attenuator
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHT4016-QEG is a 4-14GHz 6-bit digital
attenuator designed to address a dynamic of
31.5dB by 0.5dB step.
UMS
T4016
It is designed for
a
wide range of
applications, from military to commercial
communication systems.
YYWW
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form and in RoHS
compliant SMD package.

Definition of the Sij reference planes
The
reference
planes
used
for
measurements given above are symmetrical
from the symmetrical axis of the package
(see drawing beside). The input and output
reference planes are located at 3.66mm
offset (input wise and output wise
respectively) from this axis.
