LCAT7493-10

Overview

The LCAT7493-10 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 frequency range extending from 0 Hz to 6 GHz. The component features a 50 Ohm impedance and utilizes 2.2-5 connectors. It is rated for a maximum power handling capacity of 10 Watts.

Feature Summary

• Fixed attenuation design ensuring stable signal reduction across the operational bandwidth
• Broad frequency coverage supporting applications from DC up to 6 GHz
• Robust construction suitable for high-power continuous wave environments

Applications

• RF signal chain calibration and level adjustment
• Test and measurement equipment interconnects
• Communication system signal conditioning

Procurement Notes

Verify the specific connector gender configuration against project requirements, as datasheets indicate male-to-male or male-to-female variations within the series. Confirm that the 10W power rating aligns with peak and average power levels in the target application to ensure reliable operation without thermal degradation.

Selection Notes

Select this model when a precise 10 dB reduction is required within a 6 GHz bandwidth. Ensure the system impedance matches the 50 Ohm specification to maintain optimal VSWR performance. Consider the physical connector type compatibility with existing cabling infrastructure before finalizing the procurement decision.

Part Context

This component belongs to L-com's LCAT7493 series of fixed attenuators, which offers various attenuation values including 3 dB and 6 dB options. The series shares common specifications such as the 10W power rating and 2.2-5 connector interface, providing a standardized solution for diverse RF attenuation needs across different frequency applications.

Replacement Considerations

Direct substitutes include other LCAT7493 series variants with different attenuation values if the specific dB requirement changes. Cross-brand replacements must match the 10W power rating, 6 GHz frequency limit, and 50 Ohm impedance characteristics to maintain system integrity.
