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.
The circuit is delivered in a 24 Leads RoHS compliant QFN4x4 package.
