CVCO55BE-1845-1877

Overview

The CVCO55BE-1845-1877 is a voltage-controlled oscillator from the Crystek CVCO55BE series, designed for high-frequency applications. It operates within a frequency range of 1845 MHz to 1877 MHz, with a center frequency of 1861 MHz. The device utilizes a tuning voltage range of 0.5 V to 4.0 V and requires a supply voltage between 7.6 V and 8.4 V. Key performance metrics include an output power of 6 ±2 dBm, a typical second harmonic suppression of -15 dBc, and a phase noise specification of -118 dBc/Hz. It is housed in a 16-QFN package measuring 12.7 mm x 12.7 mm.

Feature Summary

• High-frequency operation capability up to 6900 MHz within the broader CVCO55BE family
• Low harmonic distortion characteristics suitable for precision signal generation
• Compact surface-mount packaging for efficient board space utilization

Applications

• Wireless communication systems requiring stable local oscillators
• Test and measurement equipment needing precise frequency synthesis
• Radar systems utilizing high-frequency signal sources

Procurement Notes

Verify that the specific part number matches the required frequency range of 1845 MHz to 1877 MHz. Confirm that the supply voltage requirements align with your system's power design, as this model specifies a range of 7.6 V to 8.4 V. Ensure compatibility with the 16-QFN package dimensions for PCB layout. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a center frequency near 1861 MHz is required with low phase noise. Consider the CVCO55BE series for higher frequency needs compared to the standard CVCO55 line. Evaluate the tuning voltage sensitivity and supply current against available control circuitry. Ensure the operating temperature range meets the environmental conditions of the intended application.

Part Context

This component belongs to the CVCO55BE series, which represents the high-frequency variant of Crystek's voltage-controlled oscillator lineup. While the standard CVCO55 covers lower frequencies, the BE series extends performance up to 6900 MHz. This specific model targets microwave applications where compact size and stable frequency generation are critical for system performance.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing should focus on the CVCO55 series or other Crystek VCOs with matching frequency ranges and package types.
