Description
The CHM1481-QFG is a 6-9GHz direct
quadrature modulator packaged integrates a
double-balanced mixer (LO suppression and
Image Rejection) and a LO buffer. It can be
used for both LSB and USB configurations.
The circuit is mainly dedicated to Point to
Point and Point to Multi-Point systems and
also well suited for a wide range of
microwave applications.
The circuit is m²anufactured with a pHEMT
process, 0.5µm gate length.
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).

Notes
ESD protections are implemented on LO port, RF port, baseband ports, drain and gate ports.
The DC connections do not include any decoupling capacitor in package, therefore it is
mandatory to provide a good external DC decoupling (10nF) on the PC board, as close as
possible to the package.
