Attenuators Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm current technical specifications and compliance status. Ensure that the SMA connector type and power ratings align with your system requirements before procurement. Cross-reference part numbers with official L3 Narda-MITEQ catalogs to avoid counterfeit components.

Attenuators Selection Notes

Select this model when a fixed 20 dB attenuation is required within a 6 GHz bandwidth. Consider the 2W power handling capability and SMA interface compatibility. Evaluate thermal management needs based on the average power rating. Compare against variable attenuators if adjustable levels are needed instead of fixed values.

Attenuators Part Context

This component belongs to the 4772 series of fixed attenuators manufactured by L3 Narda-MITEQ. The series offers various attenuation values using similar SMA inline packaging. These modules are part of a broader portfolio of passive RF components designed for military and commercial applications requiring stable performance over wide frequency ranges.

Attenuators Replacement Considerations

Compatible substitutes include other 20 dB fixed attenuators with SMA interfaces and similar power ratings. Verify frequency range coverage up to 6 GHz and VSWR specifications. Check mechanical dimensions for panel cutout compatibility. Ensure impedance matches the system standard.
