CHT4699-QDG
36-44GHz Variable Attenuator
GaAs Monolithic Microwave IC
Description
The CHT4699-QDG is a monolithic 36-
44GHz Variable Voltage Attenuator.
It is designed for a wide range of
applications, from military to commercial
communication systems.
The circuit is manufactured with a MESFET
process, 0.7µm gate length, via holes
through the substrate, air bridges.
