Procurement Notes
Verify the specific length requirements against the datasheet, as this model denotes a standard fixed length. Confirm connector gender and interface type match your system ports. Ensure environmental conditions align with the specified operating temperature range. Check for any specific RoHS compliance documentation if required by your procurement policy. Validate that the power handling capabilities meet your application's peak and average power demands before finalizing the order.
Selection Notes
Select this assembly when a rigid, durable coaxial link between two SMA female ports is required. The RG142B/U cable offers superior mechanical strength compared to flexible alternatives like RG58. Consider the 18 GHz bandwidth limit for high-frequency applications. The 50 Ohm impedance matches standard RF systems. Evaluate the fixed length constraint against routing needs in your chassis or panel design.
Part Context
This component belongs to Pasternack's line of precision coaxial cable assemblies designed for demanding RF environments. The PE7091 series typically features robust SMA connectors suitable for repeated mating cycles. These assemblies are engineered to maintain signal integrity across wide bandwidths. The specific model integrates standardized materials to ensure consistency in electrical performance and physical reliability for industrial use cases.
Replacement Considerations
Direct substitutes may include other SMA male-to-male assemblies using RG142B/U cable from different manufacturers. Verify that replacement parts match the 50 Ohm impedance and 18 GHz frequency range. Ensure connector dimensions and keying mechanisms are compatible with existing fixtures. Cross-reference VSWR and insertion loss specifications to maintain system performance levels.
