UMS CHR3663

CHR3663-QEG
RoHS COMPLIANT
17-24GHz Integrated Down Converter
GaAs Monolithic Microwave IC in SMD package
Description
The CHR3663-QEG is a multifunction part,
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
commercial
communication systems and ISM.
The circuit is manufactured with a robust
high volume pHEMT process, 0.25µm gate
length.
It is available in lead-free SMD package.

Device thermal performances
All the figures given in this section are obtained assuming that the QFN device is cooled
down only by conduction through the package thermal pad (no convection mode
considered).
The temperature is monitored at the package back-side interface (Tcase) as shown below.
The system maximum temperature must be adjusted in order to guarantee that Tcase
remains below than the maximum value specified in the next table. So, the system PCB must
be designed to comply with this requirement.
A derating must be applied on the dissipated power if the Tcase temperature can not be
maintained below than the maximum temperature specified in order to guarantee the nominal
device life time (MTTF) (see the curve Pdiss. Max).

The DC connections do not include any decoupling capacitor in package, therefore it is
mandatory to provide a good external DC decoupling on the PC board, as close as possible
