CVCO55BE-2000-2800

Overview

The CVCO55BE-2000-2800 is a voltage-controlled oscillator (VCO) from Crystek Corporation designed for high-frequency applications. It operates within a frequency range of 2000 MHz to 2800 MHz, centered at 2400 MHz. The device requires a supply voltage of 5V and draws a typical current of 25mA. Output power is specified at 5 ±5 dBm. It features a second harmonic level of -15 dBc typ and exhibits a tuning slope of 4 MHz/V. The phase noise is typically -100 dBc/Hz at 1 kHz offset. The unit supports a control voltage range of 1V to 24V and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Low phase noise performance suitable for precision RF systems
• Wide bandwidth frequency coverage across the C-band spectrum
• Integrated low harmonic distortion with suppressed secondary harmonics
• Surface-mount QFN package design for compact PCB integration

Applications

• Wireless communication base stations
• Satellite navigation receiver local oscillators
• Test and measurement equipment signal sources
• Point-to-point microwave link transceivers

Procurement Notes

Verify the specific suffix or variant designation when ordering, as Crystek may offer different pinout or tolerance variations within the CVCO55BE series. Confirm that the required frequency range aligns exactly with the 2000-2800 MHz specification. Ensure the application circuit provides a stable 5V supply and appropriate filtering for the control voltage line to maintain phase noise integrity. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions prior to final procurement.

Selection Notes

Select this component when a wide tuning range in the 2-3 GHz band is required alongside low phase noise. The 5V supply requirement simplifies power management compared to higher voltage alternatives. Consider the QFN-16 footprint for layout constraints. Compare against narrower band models if fixed frequency operation suffices. Evaluate thermal dissipation needs given the SMT package type and operating temperature limits.

Part Context

This model belongs to the CVCO55BE family, which targets high-frequency VCO applications. The BE suffix typically denotes specific high-frequency variants within the broader CVCO55 product line. Crystek designs these components to meet stringent RF performance standards. The series includes various sub-models covering different frequency bands and modulation capabilities. This specific part fills a niche for broadband C-band synthesis.

Replacement Considerations

Direct substitutes include other Crystek CVCO55BE models with overlapping frequency ranges, such as CVCO55BE-2130-2220 or CVCO55BE-3000-3100, provided the frequency span matches system requirements. Cross-brand replacements require careful verification of pin compatibility, supply voltage, and phase noise specifications. Always validate performance through prototyping before full-scale implementation.
