LCAT7491-10

Overview

The LCAT7491-10 is a fixed RF attenuator manufactured by L-com, designed for in-line module applications. It provides a nominal attenuation of 10 dB with a tolerance of ±1 dB across a frequency range from DC to 6 GHz. The component features NEX10 male to NEX10 female connectors and supports a maximum continuous wave power rating of 10 Watts. It maintains a Voltage Standing Wave Ratio (VSWR) of 1.25:1 and operates within an impedance of 50 Ohms.

Feature Summary

• NEX10 connectorized design for reliable interconnects
• High power handling capability up to 10 Watts CW
• Broadband operation covering DC to 6 GHz frequencies

Applications

• Distributed Antenna Systems (DAS)
• RF signal path attenuation
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and connector gender configuration before ordering. Confirm that the NEX10 interface matches the system requirements. Ensure the 10W power rating aligns with peak signal levels. Check for any environmental specifications if operating outside standard conditions.

Selection Notes

Select this model when a 10 dB reduction is required at frequencies up to 6 GHz. The NEX10 interface is suitable for high-power coaxial applications. Consider the 10W power limit for thermal management. Compare against other LCAT series variants for different attenuation values or connector types.

Part Context

This part belongs to the LCAT series of fixed attenuators from L-com. These components are engineered for robust performance in RF environments. The series offers various attenuation levels and power ratings. The LCAT7491-10 specifically addresses needs for moderate attenuation with high power capacity.

Replacement Considerations

Direct substitutes include the LCAT7491-10 from other authorized distributors. Verify compatibility with NEX10 connectors. Ensure equivalent electrical parameters such as 10 dB attenuation and 10W power rating. No alternative part numbers are explicitly confirmed in public documentation.
