769A-20

Attenuators Overview

The 769A-20 is a fixed coaxial attenuator from the 769A series, manufactured by L3 Narda-MITEQ. It provides a nominal attenuation of 20 dB with a tolerance of ±0.5 dB and a maximum VSWR of 1.35:1. The device operates within a frequency range of 0 Hz to 6 GHz and handles a continuous power rating of 150 Watts, with a peak power capacity of 3000 Watts. It utilizes an N-Type connector interface (N-Female input/N-Male output) in an inline module construction.

Attenuators Feature Summary

• Coaxial inline module construction for robust RF signal handling
• Fixed 20 dB attenuation value suitable for precise signal level control
• High power handling capability up to 150W continuous
• Wideband operation covering DC to 6 GHz

Attenuators Applications

• RF test and measurement setups requiring fixed signal reduction
• Microwave communication systems for power management
• Military and aerospace electronic subsystems
• Broadband instrumentation interfaces

Attenuators Procurement Notes

Verify the specific connector gender configuration (N-Female input/N-Male output) against system requirements before ordering. Confirm that the 150W continuous power rating aligns with the operational thermal environment. Ensure the 0-6 GHz frequency range meets the application's bandwidth needs. Check for any specific datasheet revisions or manufacturing lot codes if traceability is required for critical deployments.

Attenuators Selection Notes

Select this component when a fixed 20 dB attenuation is required at high power levels up to 150W. The 769A series offers a balance of wideband performance (DC-6GHz) and durability. Consider the N-Type interface compatibility with existing cabling. For applications requiring variable attenuation or lower power ratings, alternative models within the series or different product categories should be evaluated.

Attenuators Part Context

The 769A-20 belongs to the 769A series of fixed coaxial attenuators from L3 Narda-MITEQ. This series is known for its reliability in demanding environments. The manufacturer, formed from the merger of MITEQ and L3's Narda Microwave-East, specializes in microwave and RF components. The 769A series specifically targets applications needing stable attenuation values across broad frequency ranges with high power handling capabilities.

Attenuators Replacement Considerations

The 769A-30 is a confirmed substitute part number within the same series, offering 30 dB attenuation instead of 20 dB while maintaining similar power and frequency specifications. Other models in the 769A series may provide different attenuation values but share the same form factor and connector type.
