Attenuators Procurement Notes

Verify the specific part number SA18H-14 against official Fairview Microwave documentation to confirm technical specifications. Ensure compatibility with system requirements regarding frequency range, power rating, and connector type. Check for RoHS compliance status and manufacturing origin details. Confirm lead times and availability through authorized distributors or direct manufacturer channels prior to ordering.

Attenuators Selection Notes

Select this model when a fixed 14 dB attenuation is required within an 18 GHz bandwidth. Consider the 2 Watt power rating and SMA interface for system integration. Evaluate the passivated stainless steel housing for environmental protection needs. Compare VSWR performance against system reflection limits. Verify temperature operating ranges match the intended deployment environment constraints.

Attenuators Part Context

This component belongs to the Fairview Microwave SA18H series of connectorized attenuators. The series offers various attenuation values while maintaining consistent SMA interfaces and 18 GHz frequency capabilities. These devices are engineered for reliable performance in RF circuits requiring precise signal reduction without significant impedance mismatch.

Attenuators Replacement Considerations

Direct substitutes include other SA18H series models with different attenuation values if the dB requirement changes. Cross-reference with other manufacturers' SMA fixed attenuators rated for 18 GHz and similar power handling. Ensure connector polarity and impedance matching remain consistent during replacement.
