- Surface-mount construction with 0.5-inch square footprint
- Low phase noise and low harmonic generation characteristics
- Wide bandwidth frequency range operation
- Designed for high-frequency microwave applications
Applications
- Microwave communication systems
- Test and measurement equipment
- Radar systems
- Wireless infrastructure components
Procurement Notes
Verify the specific part number suffix against official Crystek Corporation documentation to ensure correct frequency range and package variant. Confirm that the 5.25V supply voltage and 50pF load capacitance requirements align with the target circuit design before procurement. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.
Selection Notes
Select this model when a surface-mount VCO is required for the 1630-1665 MHz band. Consider the 0.5-inch package size for PCB layout constraints. Ensure the application can provide the specified 5.25V supply. Evaluate phase noise requirements against system sensitivity needs. Compare against other CVCO55 variants if different frequency ranges or modulation ports are necessary.
Part Context
This component belongs to the CVCO55 series from Crystek Corporation, which offers various configurations including coaxial resonator (CC), narrow band (CL), and extra modulation port (CM) options. The BE suffix indicates a high-frequency variant within this family. The series is characterized by low phase noise and wide bandwidth capabilities suitable for demanding microwave applications.
Replacement Considerations
Direct substitutes within the same series include CVCO55BE models with adjacent frequency ranges such as CVCO55BE-2130-2220 or CVCO55BE-3000-3100, provided the frequency shift is acceptable. Verify pinout and electrical parameters match before substitution. No other manufacturer equivalents are confirmed in public documentation.
