777C-20

Attenuators Overview

The L3 Narda-MITEQ 777C-20 is a fixed precision coaxial attenuator designed for high-performance RF applications. It provides a nominal attenuation of 20 dB with a tolerance of ±0.3 dB across a frequency range from DC to 12.4 GHz. The component features Type N connectors and supports a power handling capacity of 5 watts. Key electrical specifications include a maximum VSWR of 1.20, insertion loss of 0.2 dB, and an isolation rating of 82 dB. Constructed for durability, it meets RoHS compliance standards.

Attenuators Feature Summary

• Fixed precision attenuation design ensuring stable signal reduction
• Wideband operational capability extending from DC to 12.4 GHz
• Robust construction suitable for demanding military and commercial environments

Attenuators Applications

• RF signal path calibration and testing systems
• Military communication equipment requiring precise signal levels
• Commercial microwave link infrastructure
• Laboratory measurement setups for attenuation verification

Attenuators Procurement Notes

Verify the specific connector gender (male/female) configuration required for your system integration, as datasheets may list generic Type N interfaces. Confirm that the 5W power rating aligns with your peak signal requirements to prevent damage. Ensure environmental conditions match the component's operational limits. Cross-reference the part number with official Narda-MITEQ documentation to confirm current manufacturing status and compliance certifications before finalizing procurement orders.

Attenuators Selection Notes

Select this model when a fixed 20 dB attenuation value is required within a wide bandwidth up to 12.4 GHz. Consider the 5W power handling limit against your system's maximum output power. The Type N interface dictates compatibility with existing cabling and hardware. Evaluate the ±0.3 dB tolerance against your system's precision requirements. This component is suitable for applications needing reliable, non-adjustable signal reduction without the complexity of variable attenuators.

Attenuators Part Context

The 777C-20 belongs to the Narda-MITEQ fixed attenuator series, known for high reliability in RF engineering. These components are integral to maintaining signal integrity in complex microwave systems. The product line serves both defense and commercial sectors, emphasizing durability and consistent performance. As part of the broader portfolio, it complements other passive components like couplers and switches, forming complete signal management solutions.

Attenuators Replacement Considerations

Direct substitutes must match the 20 dB nominal value, DC-12.4 GHz range, and Type N interface. Verify equivalent models from Narda-MITEQ or other manufacturers offering similar coaxial fixed attenuators. Ensure power ratings and VSWR specifications meet or exceed original requirements. Check for mechanical compatibility and mounting constraints when integrating alternative parts into existing assemblies.
