LCAT1000-20

Overview

The LCAT1000-20 is a fixed RF attenuator manufactured by L-com, designed for coaxial in-line applications. It provides a precise attenuation value of 20 dB across a frequency range from 0 Hz to 6 GHz. The component operates with a characteristic impedance of 50 Ohms and can handle a maximum power load of 2 Watts. It features SMA male connectors on one end and SMA female connectors on the other, facilitating direct connection between compatible RF systems. The unit includes a hex nut on the body for secure mounting.

Feature Summary

• Coaxial in-line design with integrated hex nut for mechanical stability
• SMA male to SMA female connector configuration for seamless integration
• Fixed 20 dB attenuation performance within specified frequency limits

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in wireless communication systems
• Protection of sensitive receiver inputs from high-power signals

Procurement Notes

Verify that the specific part number LCAT1000-20 matches the required 20 dB attenuation value and SMA connector orientation. Confirm that the 2W power rating and 6 GHz frequency limit align with your system's operational parameters. Ensure compatibility with existing SMA interfaces before procurement.

Selection Notes

Select this component when a fixed 20 dB reduction is required for frequencies up to 6 GHz. Consider the 2W power handling capacity to ensure it exceeds the expected signal power in the circuit. The SMA interface dictates compatibility with standard coaxial cables and equipment ports.

Part Context

This model belongs to the LCAT1000 series of RF fixed attenuators from L-com. The series offers various attenuation values while maintaining consistent physical dimensions and connector types. The -20 suffix specifically denotes the 20 dB attenuation level within this product family.

Replacement Considerations

Direct substitutes must match the 20 dB attenuation, 50 Ohm impedance, and SMA male-to-female configuration. Verify that alternative components support at least 2W power handling and 6 GHz frequency operation to maintain system integrity.
