779-3

Attenuators Overview

The L3 Narda-MITEQ 779-3 is a fixed precision coaxial attenuator designed for in-line RF applications. It provides a nominal attenuation of 3 dB across a frequency range from 0 MHz to 18 GHz. The component supports a maximum average input power of 2 W and utilizes an N-Type connector interface. Key performance specifications include a typical VSWR of 1.15, insertion loss of 0.2 dB, and return loss of 22 dB. It features a DC-to-18 GHz bandwidth with high stability and low reflection characteristics suitable for demanding microwave environments.

Attenuators Feature Summary

• Fixed precision attenuation design ensuring stable signal reduction
• Wideband operation covering DC to 18 GHz frequencies
• Robust coaxial construction for reliable in-line integration

Attenuators Applications

• RF test and measurement equipment calibration
• Microwave communication system signal conditioning
• Satellite communications link budget adjustment

Attenuators Procurement Notes

Verify the specific datasheet version (e.g., document 041-FIXEDATTENUATORS) against current manufacturer records to confirm mechanical dimensions and connector tolerances. Ensure the required N-Type interface matches the system board layout. Confirm that the 2 W average power rating aligns with the operational thermal environment. Cross-reference part numbers to distinguish between standard and specialized variants within the 779 series.

Attenuators Selection Notes

Select this model when a precise 3 dB reduction is required within the 18 GHz spectrum. Consider the N-Type connector compatibility with existing cabling infrastructure. Evaluate the 2 W power handling capability against peak and average signal levels. Compare VSWR and insertion loss metrics against system sensitivity requirements to ensure minimal signal degradation during transmission.

Attenuators Part Context

The 779-3 belongs to the 779 series of fixed precision coaxial attenuators manufactured by L3 Narda-MITEQ. This series includes various attenuation values such as 1, 2, 3, 4, 6, 10, and 20 dB options. The components are engineered for high reliability in military and commercial aerospace applications, offering consistent performance across wide frequency bands with durable physical construction.

Attenuators Replacement Considerations
