• Aerospace and defense radar subsystems

Attenuators Procurement Notes

Verify the specific datasheet version and manufacturer lot codes upon order confirmation. Confirm that the SMA connector gender and pin configuration match the system requirements. Ensure environmental compliance documentation aligns with project specifications. Cross-reference the part number against the latest Amphenol Narda-MITEQ catalog to confirm current production status and availability constraints.

Attenuators Selection Notes

Select this component when precise 20dB attenuation is required across a broad bandwidth extending to 40 GHz. The SMA inline form factor suits board-level or chassis-mounted designs needing compact integration. Consider the 2W power rating for moderate signal levels. Evaluate the low temperature and power coefficients for applications demanding high stability under varying thermal or load conditions compared to standard attenuators.

Attenuators Part Context

This model belongs to the 4768 series of SMA and 2.92mm mini fixed attenuators manufactured by L3 Narda-MITEQ. The series offers various attenuation values ranging from 3dB to higher increments, all sharing similar compact inline module packaging. The 4768-20 specifically addresses the need for significant signal reduction in wideband microwave environments while maintaining consistent impedance characteristics.

Attenuators Replacement Considerations

Direct substitutes within the same series include other 4768 variants with different attenuation values, such as the 4768-10 or 4768-3, if the attenuation requirement changes. For equivalent performance in different connector types, consult the manufacturer's cross-reference guide for 2.92mm or V-band alternatives. Verify that any replacement maintains the 40 GHz upper frequency limit and 2W power handling capability.
