Procurement Notes

Verify the exact part number CVCO55BE-2675-2950 against official Crystek documentation to ensure compatibility with system requirements. Confirm that the QFN-16 package dimensions and pinout match the design layout. Check for any specific handling instructions related to the surface mount technology and thermal management during assembly. Ensure that the operating voltage and current specifications align with the power supply design of the target application.

Selection Notes

Select this component when a precise VCO is needed for the 2.6–2.95 GHz range with tight phase noise requirements. Consider the 1V to 17V tuning range for flexible frequency control capabilities. Evaluate the 4 ± 2 dBm output power against downstream amplifier needs. The QFN-16 form factor is suitable for space-constrained designs requiring robust thermal performance in industrial environments.

Part Context

This model belongs to the CVCO55BE series of voltage-controlled oscillators manufactured by Crystek Microwave. These devices are engineered for high-performance RF applications requiring stable frequency generation.
