769A-10

Attenuators Overview

The L3 Narda-MITEQ 769A-10 is a fixed coaxial attenuator module designed for RF applications. It provides a nominal attenuation of 10 dB with a tolerance of ±0.4 dB across a frequency range from DC to 6 GHz. The component supports a maximum power handling capacity of 150 watts and features an input VSWR of 1.35:1 and output VSWR of 1.5:1. It utilizes Type N connectors (male/female) and operates within a temperature range of -55°C to +85°C.

Attenuators Feature Summary

• Fixed 10 dB attenuation performance
• High power handling capability up to 150 watts
• Broadband operation from DC to 6 GHz
• Robust Type N connector interface

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Attenuation stages in high-power communication systems
• Impedance matching networks requiring fixed loss
• Protection of sensitive receiver inputs from high power signals

Attenuators Procurement Notes

Verify the specific revision status, as Narda transitioned to 'A' revisions for the 769 series in August 2011. Confirm that the unit matches the required electrical specifications, particularly the 150W power rating and 10dB tolerance. Ensure connector gender compatibility (Type N M/F) aligns with system requirements before procurement.

Attenuators Selection Notes

Select this model when a fixed 10 dB loss is required at frequencies up to 6 GHz. Consider the 150W power rating for high-power environments where standard attenuators may fail. Verify that the Type N interface suits the existing cabling infrastructure. Compare against other 769A series variants if different attenuation values are needed.

Attenuators Part Context

The 769A-10 belongs to the Narda-MITEQ 769 series of fixed attenuators. This series is characterized by its ability to handle high power levels while maintaining stable performance over a wide bandwidth. The 769A series typically includes various attenuation values ranging from 3 dB to 30 dB, all sharing similar physical and electrical characteristics.

Attenuators Replacement Considerations

Direct substitutes include other models within the same 769A series, such as the 769A-3 or 769A-20, if different attenuation values are acceptable. Cross-brand replacements must match the 150W power rating, DC-6 GHz frequency range, and Type N connector type to ensure functional equivalence.
