LCAT7491-20

Overview

The LCAT7491-20 is a fixed RF attenuator manufactured by L-com, designed for in-line signal reduction applications. It provides a nominal attenuation of 20 dB with a tolerance of ±2 dB across a frequency range from DC to 6 GHz. The component supports a maximum continuous power handling capacity of 10 Watts. It features NEX10 male-to-NEX10 female connectors and maintains a voltage standing wave ratio (VSWR) of 1.25:1.

Feature Summary

• Fixed 20 dB attenuation value
• NEX10 connectorized design
• High power handling capability

Applications

• RF signal level adjustment
• Test and measurement setups
• Telecommunications equipment integration

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as the model indicates male-to-female termination. Confirm that the operating frequency does not exceed the 6 GHz upper limit and that the signal power remains within the 10 Watt continuous wave rating to ensure reliable performance and prevent component damage during installation.

Selection Notes

Select this component when a precise 20 dB reduction is required within the 6 GHz bandwidth. Ensure the application environment accommodates the NEX10 interface standard. Consider the thermal dissipation capabilities relative to the 10 Watt power rating when integrating into enclosed systems or high-density assemblies.

Part Context

This part belongs to L-com's series of coaxial fixed attenuators utilizing NEX10 interfaces. These components are engineered for stable impedance matching and low reflection characteristics. The series supports various attenuation values while maintaining consistent electrical performance across wide frequency ranges for professional RF infrastructure.

Replacement Considerations

Direct substitutes must match the 20 dB attenuation, 6 GHz frequency range, 10W power rating, and NEX10 male-to-female connector configuration. Verify that alternative parts maintain the same VSWR specifications and physical form factor for seamless integration without adapter requirements.
