LCAT1000-25

Overview

The LCAT1000-25 is a fixed RF attenuator from L-com designed for signal level reduction in coaxial systems. It provides a precise attenuation value of 25 dB across a frequency range of DC to 6 GHz. The component features a 50 Ohm impedance and supports a maximum power handling capacity of 2 Watts. It utilizes an SMA male to SMA female in-line module configuration, ensuring compatibility with standard coaxial connectors. The housing is constructed from passivated stainless steel, offering durability and environmental resistance suitable for various electronic applications requiring stable signal attenuation.

Feature Summary

• Provides fixed 25 dB attenuation for consistent signal reduction
• Operates effectively from DC up to 6 GHz frequency range
• Features SMA male to SMA female in-line connector interface
• Constructed with passivated stainless steel housing for durability

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment signal conditioning
• Circuit protection by reducing input power levels

Procurement Notes

Verify the specific part number LCAT1000-25 against official L-com documentation to confirm the 25 dB attenuation value and SMA connector type. Ensure that the required power rating of 2 Watts and frequency range up to 6 GHz align with system specifications. Check for any ordering suffixes that may indicate variations in connector plating or housing material, as these details are critical for proper integration into RF circuits.

Selection Notes

Select this component when a fixed 25 dB attenuation is required within a 50 Ohm system operating up to 6 GHz. Consider the SMA interface compatibility with existing cabling and equipment. Evaluate the 2 Watt power handling capability against peak and average signal levels to ensure reliable operation without thermal degradation. Verify that the stainless steel construction meets environmental requirements for the intended deployment scenario.

Part Context

The LCAT1000-25 belongs to L-com's passive RF attenuator series, specifically designed for fixed attenuation applications. It is part of a family of components that offer various attenuation values while maintaining consistent electrical characteristics and mechanical interfaces. This model serves as a specialized solution for precise signal control in high-frequency environments where stability and accuracy are paramount.

Replacement Considerations

Direct substitutes must match the 25 dB attenuation, 50 Ohm impedance, and SMA male-to-female configuration. Verify that alternative components support the same 2 Watt power rating and 6 GHz frequency limit. Cross-reference part numbers from other manufacturers to ensure equivalent performance metrics and physical dimensions for seamless integration.
