CHV3241-QDG Datasheet | United Monolithic Semiconductors

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 In Ga P HBT technology: 2µm emitter length, via holes through the substrate and high Q passive elements. The chip is delivered in a standard 24 Leads Ro HS pliant QFN4x4 package. Main 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 - Ro HS SMD package: 24L-QFN4x4 Main Characteristics Tamb.= +25°C Symbol Parameter Min Typ Max F_out Specified output frequency range 24 24.125 24.25 F_vco Oscillator frequency F_out/2 IF_out Output Intermediate frequency (IF) F_out/1024 P_out Output power at F_out Pres_P Output power at (IF) PN SSB Phase Noise @ F_out @ 100k Hz -94 ESD Protection: Electrostatic discharge sensitive device.
