Attenuators Procurement Notes

Verify the specific datasheet version for the SA18H-01 to confirm current RoHS compliance status and detailed mechanical dimensions. Ensure that the SMA connector gender configuration matches the system requirements. Cross-reference the manufacturer's official documentation for any updates regarding material specifications or environmental operating limits before finalizing procurement decisions.

Attenuators Selection Notes

Select the SA18H-01 when a low attenuation value of 1 dB is required for high-frequency applications up to 18 GHz. This model is suitable for systems requiring a 50 Ohm impedance match and a 2 W power handling capacity. Consider the SMA interface compatibility and the stainless steel body material for environmental resilience when integrating this attenuator into RF designs.

Attenuators Part Context

The SA18H-01 belongs to the SA18H series of fixed attenuators from Fairview Microwave. This series is characterized by its use of SMA connectors and operation up to 18 GHz. Other models in the series offer different attenuation values, such as SA18H-03 for 3 dB and SA18H-10 for 10 dB, all sharing similar structural and performance characteristics including the stainless steel body and 2 W power rating.
