CVCO55BE-1750-2150

Overview

The CVCO55BE-1750-2150 is a Voltage Controlled Oscillator (VCO) from the Crystek CVCO55 series, designed for microwave applications. It operates within a frequency range of 950 MHz to 2050 MHz, with a typical center frequency specification aligned with this band. The device utilizes a tuning voltage range of 0.3 V to 4.7 V and requires a 5 V supply voltage. Key electrical characteristics include an output power of -5.0 ±1 dBm, a maximum supply current of 40 mA, and a second harmonic suppression of typically -20 dBc. Phase noise performance is specified at -118 dBc/Hz, with a pushing factor of 0.5 MHz/V. The component is housed in a 16-QFN package measuring 12.70mm x 12.70mm x 5.59mm and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides stable voltage-controlled oscillation across a wide microwave frequency band suitable for communication systems.
• Features low phase noise performance to ensure signal integrity in sensitive RF applications.
• Utilizes a compact surface-mount QFN package for efficient PCB layout and integration.

Applications

• Wireless communication transceivers
• Local oscillator sources in RF receivers
• Frequency synthesis circuits

Procurement Notes

Verify the specific datasheet version for the CVCO55BE-1750-2150 model, as Crystek documentation often lists generic parameters for the CVCO55BE series. Confirm that the 950-2050 MHz range and associated electrical specs apply to this exact part number variant. Ensure compatibility with RoHS3 compliance requirements if mandated by your project specifications. Cross-reference the 16-QFN footprint dimensions against your board design files prior to procurement.

Selection Notes

Select this component when a wide tuning range covering up to 2050 MHz is required with moderate output power levels. The -5 dBm output power suits direct drive applications without additional amplification. Consider the 0.5 MHz/V pushing factor for frequency stability under supply variations. The -40°C to 85°C temperature range allows for industrial environment deployment. Compare against other CVCO55 variants if narrower bandwidth or different frequency centers are needed.

Part Context

This VCO belongs to the CVCO55 series, which includes various models like CVCO55CC-0444-0485 and CVCO55BE-2300-2400. While the CC series covers lower frequencies around 464.5 MHz, the BE series targets higher microwave bands. The CVCO55BE-1750-2150 shares the same physical package and basic electrical architecture as other BE series parts but differs in its specific frequency tuning range and internal resonator configuration.

Replacement Considerations

Direct substitutes may include other CVCO55BE models such as CVCO55BE-1600-1850 or CVCO55BE-2300-2400 if their respective frequency ranges overlap with system requirements. Verify that the replacement part maintains the same 16-QFN package and pinout compatibility. Check if the phase noise and output power specifications of alternative parts meet the original design margins.
