LCAT7490-10

Overview

The LCAT7490-10 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 power handling capacity of 5 Watts. The device operates over a frequency range from DC to 6 GHz and maintains a characteristic impedance of 50 Ohms. It features NEX10 connectors, specifically configured as male-to-female, ensuring compatibility within standard RF interconnect systems.

Feature Summary

• Fixed attenuation value of 10 dB
• Operates from DC to 6 GHz
• NEX10 connectorized design
• 5 Watt power rating

Applications

• RF signal level reduction
• Impedance matching in communication systems
• Test and measurement setups

Procurement Notes

Verify the specific connector gender configuration (male-to-female) against system requirements. Confirm that the 5W power rating and 6GHz frequency limit align with operational parameters. Ensure the NEX10 interface matches existing cabling infrastructure to prevent mismatch losses or physical incompatibility during installation.

Selection Notes

Select this component when a precise 10 dB reduction is required within the 6 GHz bandwidth. Consider the 5W power handling capability for high-power RF paths. The NEX10 interface dictates cable compatibility; ensure mating connectors are available. Evaluate thermal management needs if continuous operation approaches the maximum power rating.

Part Context

This model belongs to the LCAT7490 series of fixed attenuators from L-com. Other variants in the series include different attenuation values such as 6 dB and 20 dB, sharing similar form factors and connector types. The series supports general RF attenuation needs across various communication frequencies up to 6 GHz.

Replacement Considerations

Direct substitutes may include other LCAT7490 series models with identical connector interfaces but different attenuation values if adjustable levels are needed. Cross-brand replacements must match the NEX10 interface, 50 Ohm impedance, and 6 GHz frequency range.
