Attenuators Procurement Notes

Verify the specific connector gender and pin configuration against the official datasheet before procurement. Confirm that the SMA.86 interface matches the system requirements. Check RoHS compliance status and environmental certifications if required for the specific application environment. Ensure the 2W power rating aligns with the expected signal levels in the target circuit to prevent damage.

Attenuators Selection Notes

Select this model when a precise 20 dB reduction is required at frequencies extending to 26.5 GHz. The SMA.86 interface dictates compatibility with existing SMA-based infrastructure. Consider the 2W power handling capability relative to the input signal strength. The wide temperature range makes it suitable for harsh environments where standard components might fail. Verify physical dimensions fit within the available space constraints.

Attenuators Part Context

This component belongs to Radiall's series of connectorized attenuators designed for interconnect applications. It serves as a passive RF component used to reduce signal amplitude without significant distortion. The product line focuses on high-reliability solutions for demanding electronic systems. The specific model integrates precision internal elements to maintain consistent attenuation across the specified bandwidth.

Attenuators Replacement Considerations

Direct substitutes include other Radiall models with identical electrical specifications and connector types. Cross-reference part numbers such as R413820000 for lower frequency variants or R413813121 for different attenuation values. Ensure any replacement maintains the SMA.86 interface and 50 Ohm impedance. Verify that alternative sources provide equivalent performance data and reliability ratings.
