757C-10

Attenuators Overview

The L3 Narda-MITEQ 757C-10 is a fixed attenuator designed for RF and microwave applications. It provides a nominal attenuation of 10 dB with a frequency range extending from 0 MHz to 12,400 MHz. The device features a tolerance of ±0.3 dB and includes a maximum VSWR of 1.25. Physical dimensions include a diameter of 0.82 inches (20.8 mm) and a length of 1.20 inches (30.5 mm). It operates within a temperature range of -55°C to +85°C and supports a maximum DC voltage of 1000V.

Attenuators Feature Summary

• Provides precise 10 dB fixed signal attenuation across a broad DC to 12.4 GHz bandwidth
• Constructed with robust mechanical design suitable for high-power RF environments
• Maintains stable performance characteristics under extreme temperature variations

Attenuators Applications

• RF test and measurement instrumentation
• Microwave communication systems
• Signal conditioning in radar equipment

Attenuators Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing specifications may evolve. Confirm that the required attenuation value matches the 10 dB specification exactly. Ensure environmental ratings meet the operational temperature requirements of the target system. Cross-reference physical dimensions against existing chassis or mounting constraints before finalizing procurement decisions.

Attenuators Selection Notes

Select this component when a fixed 10 dB loss is required up to 12.4 GHz. Consider the physical size constraints due to its cylindrical form factor. Evaluate if the specified VSWR meets system impedance matching requirements. Compare against adjustable alternatives only if variable attenuation is necessary, noting this model is fixed.

Attenuators Part Context

This part belongs to the 757C series of fixed attenuators manufactured by L3 Narda-MITEQ. The series includes variants with different attenuation values, such as the 757C-3 and 757C-20. These components are widely used in professional RF engineering contexts requiring reliable signal reduction without active power sources.

Attenuators Replacement Considerations

Direct substitutes include other models from the same 757C series with identical 10 dB attenuation. Verify compatibility with connector types and mounting styles when considering cross-brand alternatives.
