779-20

Attenuators Overview

The L3 Narda-MITEQ 779-20 is a fixed precision coaxial attenuator designed for high-frequency applications. It provides a nominal attenuation of 20 dB with a frequency range extending from DC to 18 GHz. The component supports a maximum average input power of 2 Watts. It features a Type N connector interface and maintains a typical VSWR of 1.30:1 across the operating band. The unit exhibits low insertion loss characteristics, ensuring signal integrity in RF systems.

Attenuators Feature Summary

• Fixed precision attenuation design for stable signal reduction
• Wideband operation covering DC to 18 GHz frequencies
• Robust construction suitable for demanding RF environments

Attenuators Applications

• RF test and measurement equipment calibration
• Microwave communication system signal conditioning
• Defense and aerospace radar subsystems

Attenuators Procurement Notes

Verify the specific datasheet version for the 779-20 model to confirm exact dimensional tolerances and connector specifications. Ensure compatibility with existing Type N interfaces in your assembly. Cross-reference the RoHS compliance status if environmental regulations apply to your deployment. Confirm the active product status with the supplier before finalizing orders.

Attenuators Selection Notes

Select this component when a precise 20 dB reduction is required within an 18 GHz bandwidth. Consider the 2W power handling capability against your system's peak and average power levels. Evaluate the VSWR performance to ensure it meets your return loss requirements. Compare physical dimensions against available space constraints in your chassis or module design.

Attenuators Part Context

This part belongs to the 779 series of fixed coaxial attenuators manufactured by L3 Narda-MITEQ. The series includes various attenuation values such as 1, 3, 6, 10, and 30 dB variants. These components are engineered for consistency and reliability in microwave applications, sharing common form factors and connector types within the family.

Attenuators Replacement Considerations

Direct substitutes may include other 20 dB fixed attenuators from the same 779 series or equivalent models from other manufacturers offering Type N connectors and DC-18 GHz coverage. Verify that replacement parts match the 2W power rating and 20 dB nominal attenuation exactly.
