CHV2412-QDG Fully integrated HBT K-Band VCO Description The CHV2412-QDG is a monolithic multifunction for frequency generation. It integrates an X-band "push-push" oscillator with frequency control (VCO) thanks to base-collector diodes used as varactors, a Kband buffer amplifiers and a divider by 8. All the active devices are internally self-biased. UMS UMS V2412 A3667A A3688A YYWW YYWWG Plastic package The circuit is delivered 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 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 the maximum temperature specified (see the curve Pdiss. Max) in order to guarantee the nominal device life time (MTTF). Ref. : DSCHV2412-QDG4120 - 30 Apr 14 4/11 Specifications subject to change without notice Bât.
