CHT4690-99F
RoHS COMPLIANT
5-30GHz ATTENUATOR
Description
GaAs Monolithic Microwave IC
The CHT4690 is a variable 5-30GHz
attenuator designed for a wide range of
applications, from military to commercial
communication systems. The backside of the
chip is both RF and DC grounds. This helps
simplify the assembly process.
The circuit is manufactured with a MESFET
process, 0.7µm gate length, via holes through
the substrate and air bridges.
It is supplied in chip form.
