CHT4690 Datasheet, PDF (1/13 Pages) United Monolithic Semiconductors – 5-30GHz ATTENUATOR

CHT4690
RoHS COMPLIANT
5-30GHz ATTENUATOR
GaAs Monolithic Microwave IC
Description
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.
