LCAT7437-1

Overview

The LCAT7437-1 is a fixed RF attenuator from the LCAT7437 series manufactured by L-com. It provides a precise attenuation value of 1 dB with an impedance of 50 ohms. The device operates within a frequency range of 0 Hz to 4 GHz and supports an input power rating of 2W. It features a BNC plug-to-BNC jack interface configuration, making it suitable for in-line signal reduction applications.

Feature Summary

• Provides fixed 1 dB attenuation for signal level adjustment
• Features BNC male-to-female connector interface for direct integration
• Constructed with brass body material for durability

Applications

• RF signal path attenuation
• Test and measurement equipment interconnects
• Communication system signal conditioning

Procurement Notes

Verify that the specific part number LCAT7437-1 matches the required 1 dB attenuation value, as other variants in the LCAT7437 series offer different attenuation levels such as 2 dB or 4 dB. Confirm the BNC interface type and 50 ohm impedance requirements align with your system design before procurement.

Selection Notes

Select this component when a fixed 1 dB reduction is required at frequencies up to 4 GHz. Ensure the 2W power handling capacity meets the system's maximum input power. The brass construction and BNC connectors are standard for general-purpose RF applications requiring reliable mechanical connection.

Part Context

This component belongs to the LCAT7437 series of fixed RF attenuators. The series includes variants with different attenuation values, such as LCAT7437-2 (2 dB) and LCAT7437-4 (4 dB), all sharing similar physical interfaces and power ratings but differing in their specific attenuation specifications.

Replacement Considerations

Direct substitutes include other LCAT7437 series models if the attenuation value differs, or equivalent 1 dB BNC fixed attenuators from other manufacturers with matching 50 ohm impedance and 4 GHz frequency range.
