Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm the exact attenuation value and connector gender configuration. Ensure that the required operating temperature range aligns with the specified -65°C to +165°C limits. Confirm compatibility with the intended cable type, noting the 2 GHz support limit for associated cabling. Cross-reference the non-screened designation with system shielding requirements before procurement.

Selection Notes

Select this component when a precise 9 dB attenuation is required for SMA interfaces in harsh environments. Consider the 18 GHz maximum frequency capability for high-speed signal integrity. Evaluate the non-screened construction against electromagnetic interference requirements. Verify power handling capabilities if significant thermal dissipation is expected during operation.
