LCAT7437-5

Overview

The LCAT7437-5 is a fixed RF attenuator manufactured by L-com, designed for signal level reduction in radio frequency circuits. It features a BNC plug-to-jack interface configuration with a nominal attenuation value of 5 dB. The component operates within a frequency range of DC to 4 GHz and maintains a characteristic impedance of 50 ohms. It supports an input power rating of 2 watts and utilizes brass construction with gold plating for the connector contacts.

Feature Summary

• Fixed attenuation design providing consistent signal reduction
• BNC male-to-female interconnect configuration
• Gold-plated contact surfaces for reliable conductivity

Applications

• RF signal path conditioning
• Test and measurement equipment connections
• Wireless communication system integration

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct attenuation values and interface types. Confirm that the required frequency range and power handling capabilities align with the application requirements before procurement. Cross-reference datasheet specifications for environmental operating limits.

Selection Notes

Select this component when a precise 5 dB reduction is required at frequencies up to 4 GHz. Ensure the system impedance matches the 50-ohm specification to minimize reflections. Consider the physical BNC connector size and mating compatibility with existing test fixtures or circuit boards.

Part Context

This model belongs to the LCAT series of fixed attenuators from L-com. The series offers various attenuation values while maintaining consistent mechanical interfaces and electrical performance characteristics across different models. These components are standard interconnect solutions for RF applications requiring stable signal levels.

Replacement Considerations

Compatible substitutes include other LCAT series models with identical BNC interfaces but different attenuation values, such as LCAT7437-10 or LCAT7437-20, provided the specific dB reduction requirement differs. Verify impedance and frequency range compatibility when selecting alternatives.
