CHR3764-QEG Datasheet, PDF (1/18 Pages) United Monolithic Semiconductors – 21-27GHz Down-Converter

CHR3764-QEG
RoHS COMPLIANT
21-27GHz Down-Converter
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHR3764-QEG is a multifunction
monolithic circuit, which integrates a
balanced cold FET mixer, a multiplier by two,
and a RF LNA including gain control.
It is designed for a wide range of
applications, typically ISM and 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.
