CHV3241-QDG
RoHS COMPLIANT
Fully Integrated HBT K-band VCO
GaAs Monolithic Microwave IC In QFN package
Description
The CHV3241-QDG is a monolithic
multifunction circuit suitable 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 amplifier and a divider by 512. All
the active devices are internally self-biased.
The circuit is fully integrated on InGaP HBT
technology: 2µm emitter length, via holes
through the substrate and high Q passive
elements.
The chip is delivered in a standard 24 Leads
RoHS compliant QFN4x4 package.
Main Features
K-band VCO & K-band buffer
