CHV2421-QDG
RoHS compliant
24-24.5GHz Tx Multifunction
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHV2421-QDG is a monolithic
multifunction for dual channel frequency
generation. It integrates a X-band “push-
push” oscillator with frequency control thanks
to base collector diodes, used as varactors,
two K-Band buffers with a “Mute” power
control command (M1 ,M2) for each output,
and a frequency divider by 8.
The circuit is dedicated to sensors and also
well suited for a wide range of microwave
and millimeter wave applications and
systems.
The circuit is manufactured with a standard
InGaP HBT process, 2µm emitter length, via
holes through the substrate, and high Q
passive elements.
It is supplied in a 24 leads RoHS compliant
QFN4x4 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 (see the curve Pdiss. Max) in
order to guarantee the nominal device life time (MTTF).

: 150 °C
Junction temperature absolute maximum rating
: 175 °C
Max. continuous dissipated power @ Tcase=

(2) Derating at junction temperature constant = Tj max
(3) Rth J -C is calculated for a worst case where the hottest junction of the MMIC is considered, and all component biasing are
supplied.
(4) Tcase=Package back side temperature measured under the die -attach-pad (see the drawing below).
