CHR3861-QEG
RoHS COMPLIANT
6-9GHz Integrated Down Converter
GaAs Monolithic Microwave IC in SMD package
Description
The CHR3861-QEG is a multifunction part,
which integrates a balanced cold FET mixer,
a LO bufffer, 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 on a pHEMT
process, 0.25µm gate length.
It is supplied in lead-free SMD package.
