CHV3241-QDG_15 Datasheet, PDF (1/14 Pages) United Monolithic Semiconductors – Fully Integrated HBT K-band VCO

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

with low pulling, for optimum efficiency
 Fully integrated VCO (no external
Resonator)
 Low phase noise
 High temperature range
 High output power
 4^th amplifier bias usable for power setting
 High frequency stability
 On chip self biased devices
 RoHS SMD package: 24L-QFN4x4
