LCAT7396-1

Overview

The L-com LCAT7396-1 is a fixed attenuator module designed for RF applications. It provides an attenuation value of 1 dB with a characteristic impedance of 75 Ohms. The device operates within a frequency range of 0 Hz to 3 GHz and supports a maximum power handling capacity of 2 Watts. It utilizes F-type connectors, featuring an F-type male input and an F-type female output. This inline module is constructed from brass with tri-metal contacts and gold plating, ensuring reliable signal transmission in coaxial systems.

Feature Summary

• Provides precise 1 dB fixed attenuation for signal level adjustment
• Operates effectively across a broad frequency spectrum up to 3 GHz
• Features robust brass construction with gold-plated tri-metal contacts
• Designed for easy integration using standard F-type coaxial connectors

Applications

• RF signal distribution networks requiring precise attenuation
• Cable television (CATV) system installations
• Broadband communication infrastructure testing
• Coaxial cable assembly and maintenance

Procurement Notes

Verify the specific model suffix corresponds to the required attenuation value, as the LCAT7396 series includes variants with different dB ratings. Confirm that the 75 Ohm impedance matches your system requirements, as this component is not compatible with 50 Ohm environments. Ensure the F-type connector interface aligns with existing cabling. Check for any updated datasheets regarding power handling limits at higher frequencies to prevent signal degradation or component damage during operation.

Selection Notes

Select this component when a low attenuation value of 1 dB is necessary for fine-tuning signal levels in 75 Ohm systems. Consider the 2 Watt power rating to ensure it exceeds the expected signal power in the application path. The F-type connector choice dictates compatibility with legacy or specific coaxial standards. Evaluate the operating frequency range to confirm coverage up to 3 GHz meets the highest frequency signals present in the network.

Part Context

This part belongs to the LCAT7396 series of line modules manufactured by L-com. These modules are standardized fixed attenuators used primarily in video and RF distribution contexts. The series offers various attenuation values, allowing engineers to build custom signal chains. The LCAT7396-1 specifically addresses scenarios requiring minimal signal reduction while maintaining impedance integrity in high-frequency coaxial environments.

Replacement Considerations

Compatible substitutes include other L-com models such as LCAT7396-2 or LCAT7396-6 if different attenuation values are acceptable. Third-party manufacturers producing 75 Ohm, F-type, 1 dB fixed attenuators may also serve as replacements, provided they meet the 2 Watt power and 3 GHz frequency specifications. Verify connector gender and plating material to ensure physical and electrical compatibility.
