LCAT7437-10

Overview

The LCAT7437-10 is a fixed RF attenuator manufactured by L-com, designed for in-line coaxial applications. It provides a precise attenuation value of 10 dB across a frequency range extending from DC to 4 GHz. The component features a 50-ohm impedance characteristic and is rated to handle up to 2 Watts of power. Its physical construction utilizes brass material, ensuring durability and consistent performance in various RF environments.

Feature Summary

• Provides fixed 10 dB signal attenuation
• Operates within DC to 4 GHz frequency range
• Features BNC male to BNC female interface
• Rated for 2 Watts power handling capacity

Applications

• RF signal level reduction in test setups
• Impedance matching in 50-ohm systems
• Protection of sensitive receiver inputs
• Signal conditioning in coaxial networks

Procurement Notes

Verify the specific part number LCAT7437-10 against official L-com documentation to confirm the 10 dB attenuation value and 4 GHz upper frequency limit. Ensure compatibility with BNC connectors and 50-ohm system requirements before integration into existing RF infrastructure.

Selection Notes

Select this component when a fixed 10 dB attenuation is required between DC and 4 GHz. The BNC plug-to-jack configuration suits direct cable connections. Verify that the 2 Watt power rating meets the application's peak power demands and that the brass housing is suitable for the environmental conditions.

Part Context

This model belongs to L-com's series of fixed attenuators, which offer various attenuation values while maintaining consistent BNC connectivity. The LCAT7437-10 specifically addresses needs for moderate signal reduction in standard 50-ohm coaxial systems, providing a reliable solution for frequency ranges up to 4 GHz.

Replacement Considerations

Compatible substitutes include other L-com models such as LCAT7437-4 or LCAT7437-6 if different attenuation values are acceptable, provided they share the same BNC interface and frequency/power specifications.
