LCAT7609-3

Overview

The LCAT7609-3 is a fixed RF attenuator manufactured by L-com, designed for use in radio frequency applications. It provides a precise attenuation value of 3dB with a nominal impedance of 50 Ohms. The component operates within a frequency range of 0 Hz to 3 GHz and can handle a maximum power rating of 2W. It features TNC single receptacle connectors for secure cable attachment. This device is part of the LCA series and is currently listed as an active product in the manufacturer's catalog.

Feature Summary

• Provides fixed 3dB signal attenuation for RF circuitry
• Maintains 50 Ohm impedance matching across the operational bandwidth
• Utilizes TNC single receptacle interface for reliable connection
• Rated for 2W power handling capacity

Applications

• RF signal level adjustment in test and measurement equipment
• Impedance matching in wireless communication systems
• Signal conditioning in industrial automation networks
• Component integration in machine vision applications

Procurement Notes

Verify the specific datasheet version when ordering, as technical specifications may be updated by the manufacturer. Confirm that the TNC connector type matches your existing cabling infrastructure. Ensure the 2W power rating and 3GHz frequency limit are sufficient for your intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 3dB reduction is required in a 50 Ohm system operating below 3 GHz. Consider the TNC interface compatibility with your current assembly. Evaluate the 2W power handling against peak signal levels to prevent damage. Compare against other LCA series variants if different attenuation values or connector types are needed.

Part Context

This component belongs to the LCA series of fixed attenuators from L-com, a brand specializing in copper and fiber cable assemblies and RF accessories. The series focuses on providing reliable passive components for industrial and commercial connectivity solutions. L-com products are generally distributed through authorized electronic component channels and specialized cable manufacturers.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include FMAT7609-3 (Fairview Microwave), PE7609-3 (Pasternack), and R414503000 (Radiall). These alternatives share similar electrical characteristics such as 3dB attenuation, 50 Ohm impedance, and TNC interfaces. Verify mechanical dimensions and connector gender compatibility before substitution.
