CHR3762-QDG
5.5-9GHz Integrated Down Converter
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHR3762-QDG is a multifunction
monolithic receiver, which integrates a
balanced cold FET mixer, a LO buffer, and a
RF low noise amplifier.
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.
