CHT3029-QEG
DC-31GHz 4Bit Digital Attenuator
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHT3029-QEG is a very wide band
digital attenuator, which integrates 4 bits with
a LSB of 1dB and provides a dynamic range
of 15dB from DC to 31GHz.
It is designed for a wide range of
applications, from military to commercial
communication systems.
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 supplied in RoHS compliant SMD
package.
