CHV2411AQDG

CHV2411aQDG Fully Integrated HBT K-band VCO GaAs Monolithic Microwave IC in QFN package Description The CHV2411aQDG 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 K-band buffer amplifiers and a divider by 8. The VCO is fully integrated on HBT process. All the active devices are internally self-biased. The circuit is fully integrated on InGaP HBT process: 2µm emitter length, via holes through the substrate and high Q passive elements. The chip is delivered in a 24 Leads RoHS compliant QFN4x4 package.
