CHV3241-QDG - Fully Integrated HBT K-band VCO

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.

Features

  • K-band VCO & K-band buffer.
  • Prescaler/512 generating 24MHz output suitable for software frequency loop.
  • Prescaler and buffer switching capability with low pulling, for optimum efficiency.
  • Fully integrated VCO (no external Resonator).
  • Low phase noise.
  • High temperature range.
  • High output power.
  • 4th amplifier bias usable for power setting.
  • High frequency stability.
  • On chip self biased devices.
  • RoHS SMD package: 24L-QFN4x4 Main Characteristics.

CHV3241-QDG 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.
