17-27GHz Down-Converter
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHR3664-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.

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 cannot be
maintained below than the maximum temperature specified (see the curve Pdiss. Max) in
order to guarantee the nominal device life time (MTTF).
Recommended max. junction temperature (Tj max) : 124 °C
Junction temperature absolute maximum rating : 175 °C
Max. continuous dissipated power (Pdiss. Max.) : 1.3 W
=>
Pdiss. Max. derating above Tcase(1)=85 °C :33 mW/°C
Junction-Case thermal resistance (Rth J-C)(2) : <30 °C/W
Minimum Tcase operating temperature(3) : -40 °C
Maximum Tcase operating temperature(3) :85 °C
Minimum storage temperature : -55 °C
Maximum storage temperature : 150 °C
(1) Derating at junction temperature constant = Tj max.
(2) Rth J-C is calculated for a worst case considering the hottest junction of the MMIC and all the devices biased.
(3) Tcase=Package back side temperature measured under the die-attach-pad (see the drawing below).

(1) The package outline drawing included to this data-sheet is given for indication. Refer to the
application note AN0017 (http://www.ums-gaas.com) for exact package dimensions.
(2) It is strongly recommended to ground all pins marked “Gnd” through the PCB board.
Ensure that the PCB board is designed to provide the best possible ground to the package.

Notes
Due to ESD protection circuits on RF and LO inputs, an external capacitance might be
requested to isolate the product from external voltage that could be present on these
accesses in the application.
ESD protections are implemented on gate accesses.
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
to the package.
