Procurement Notes
Verify part authenticity through authorized Crystek distributors or certified suppliers. Confirm that the received component matches the exact model designation and package specifications. Check for physical damage or contamination before installation. Ensure storage conditions comply with manufacturer guidelines to maintain performance integrity. Validate supplier documentation against official Crystek product records.
Selection Notes
Select this component when a fixed-frequency VCO within the 1.52–1.635 GHz range is required. Consider the specific output power and tuning sensitivity requirements for the target application. Evaluate the surface-mount package size constraints against available PCB space. Assess thermal management needs based on the specified operating temperature range.
Part Context
This model belongs to the CVCO55 series of voltage-controlled oscillators produced by Crystek Corporation. The series typically offers various frequency options tailored for different RF applications. Components in this family share similar packaging and operational characteristics while differing in specific frequency parameters.
Replacement Considerations
No public substitute part numbers are confirmed for this specific model. Verify compatibility carefully if considering alternative VCOs, as frequency ranges and electrical characteristics must match precisely.
