CHV2421-QDG RoHS compliant 24-24.5GHz Tx Multifunction GaAs Monolithic Microwave IC in SMD leadless package Description UMS UMS V2421 A3667A A3688A YYWW YYWWG The CHV2421-QDG is a monolithic multifunction for dual channel frequency generation. It integrates a X-band “pushpush” 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.

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).
