LCAT7609-6

Overview

The LCAT7609-6 is a fixed RF attenuator manufactured by L-com, designed for coaxial signal applications. It provides an attenuation value of 6 dB with a characteristic impedance of 50 ohms. The device supports a maximum power handling capacity of 2 watts and operates within a frequency range from DC to 3 GHz. The unit features a brass body construction and utilizes TNC connectors, specifically configured as a male plug to female jack interface.

Feature Summary

• Provides precise 6 dB signal attenuation in a 50-ohm system
• Operates reliably across a frequency spectrum from DC to 3 GHz
• Constructed with a durable brass housing for thermal stability
• Utilizes standard TNC male-to-female coaxial connectivity

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching between components in wireless communication systems
• Protection of sensitive receiver inputs from high-power signals
• Integration into coaxial cable assemblies requiring fixed loss

Procurement Notes

Verify the specific connector gender configuration matches the required circuit topology, as TNC interfaces are directional. Confirm that the operating frequency does not exceed the 3 GHz upper limit to ensure performance integrity. Ensure the signal power remains within the 2-watt rating to prevent component damage. Check for surface finish specifications if environmental corrosion resistance is a critical requirement for the installation site.

Selection Notes

Select this model when a fixed 6 dB loss is required in a 50-ohm environment. Consider the brass material properties for thermal management compared to other alloys. Evaluate the TNC interface compatibility against existing cabling infrastructure. Assess whether the DC to 3 GHz bandwidth covers all operational frequencies of the target application without significant deviation.

Part Context

This component belongs to the LCAT7609 series of fixed attenuators from L-com. The series offers various attenuation values while maintaining consistent 50-ohm impedance and TNC connectivity. The LCAT7609-6 specifically addresses applications needing moderate signal reduction. The series is designed for general-purpose RF engineering tasks requiring reliable coaxial interconnects.

Replacement Considerations

Compatible substitutes include models with identical 6 dB attenuation, 50-ohm impedance, and TNC male-to-female interfaces. Verify that alternative parts support the same 2-watt power rating and 3 GHz frequency range. Ensure physical dimensions and mounting requirements match the existing assembly constraints.
