LCAT7437-3

Overview

The LCAT7437-3 is a fixed RF attenuator from the L-com LCAT7437 series, designed for in-line signal reduction. It provides a precise attenuation value of 3 dB across a frequency range of DC to 4 GHz. The component features BNC male-to-female connectors and operates with a maximum input power of 2W. Constructed from tri-metal plated brass, it ensures durability and consistent performance in high-frequency applications requiring stable impedance matching.

Feature Summary

• Provides fixed 3 dB attenuation for signal level control
• Operates reliably within a DC to 4 GHz frequency range
• Features robust BNC plug-to-jack interface connectivity

Applications

• Wireless communication systems
• Satellite communication networks
• Signal strength optimization in RF circuits

Procurement Notes

Verify the specific part number LCAT7437-3 against official L-com documentation to confirm the 3 dB attenuation rating and 2W power handling capabilities. Ensure compatibility with BNC connector types and 50 Ohm system impedance requirements before procurement. Cross-reference datasheets for environmental specifications and material composition details.

Selection Notes

Select this component when a fixed 3 dB reduction is required for signals up to 4 GHz. Consider the 2W power rating and BNC interface compatibility with existing test or communication equipment. Evaluate the tri-metal plated brass construction for environmental resilience in deployed systems.

Part Context

This model belongs to the LCAT7437 series of coaxial attenuators. The series offers various attenuation values while maintaining consistent mechanical interfaces and power ratings. The LCAT7437-3 specifically addresses applications needing moderate signal reduction without affecting higher frequency integrity.

Replacement Considerations

Compatible substitutes include other LCAT7437 series variants with different attenuation values, such as LCAT7437-4 (4 dB) or LCAT7437-20 (20 dB), provided the specific attenuation requirement differs. Ensure replacement parts maintain the same BNC interface and 2W power rating.
