Attenuators Procurement Notes

Verify the specific part number SA18H-13 against official Fairview Microwave documentation to confirm the 13 dB attenuation value and SMA interface type. Ensure that the required 2W power rating and 18 GHz frequency range align with your system specifications. Check for RoHS compliance status and confirm the operating temperature limits meet environmental requirements before finalizing procurement orders.

Attenuators Selection Notes

Select this component when a precise 13 dB reduction is required within an 18 GHz bandwidth. The SMA interface ensures compatibility with standard coaxial systems. Consider the 2W power handling capacity and the wide operating temperature range for robust performance. Verify that the 50 Ohm impedance matches the rest of the transmission line to minimize reflections and maintain signal integrity across the specified frequency spectrum.

Attenuators Part Context

This model belongs to the Fairview Microwave series of connectorized fixed attenuators. These components are engineered to provide stable attenuation values across wide frequency bands. The series typically offers various attenuation levels while maintaining consistent VSWR and power handling capabilities. The SA18H-13 specifically addresses needs for moderate signal reduction in high-frequency RF environments using durable metallic housing.

Attenuators Replacement Considerations

Direct substitutes must match the 13 dB attenuation, SMA plug-to-jack interface, 50 Ohm impedance, and 18 GHz frequency limit. Equivalent parts should also support at least 2W input power and similar VSWR characteristics. Verify thermal ratings and physical dimensions to ensure mechanical fit. Cross-reference manufacturer datasheets to confirm electrical parameter equivalence.
