LCAT1000-12

Overview

The LCAT1000-12 is a fixed RF attenuator manufactured by L-com, designed for coaxial in-line applications. It provides a nominal attenuation of 12 dB with a frequency range extending from DC to 6 GHz. The component features SMA male connectors on both ends and operates within a 50 Ohm impedance system. It supports a maximum power handling capacity of 2 Watts. The body is constructed from stainless steel and includes a hex nut for secure installation.

Feature Summary

• Coaxial in-line design with SMA male-to-male connectivity
• Stainless steel housing for durability
• Fixed 12 dB attenuation value

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in microwave circuits
• Signal conditioning in communication systems

Procurement Notes

Verify the specific datasheet version for precise mechanical dimensions and tolerance specifications. Confirm connector gender compatibility with existing SMA interfaces. Ensure operating power levels remain within the 2W limit to prevent damage. Check for any environmental rating requirements if used in harsh conditions.

Selection Notes

Select this model when a fixed 12 dB attenuation is required at frequencies up to 6 GHz. Consider the SMA interface type for compatibility with standard RF components. Evaluate the 2W power rating against system signal levels. Stainless steel construction offers robustness for industrial or outdoor deployments.

Part Context

This part belongs to the LCAT1000 series of fixed attenuators from L-com. Variants in this series differ primarily in attenuation values, such as the LCAT1000-25 offering 25 dB. All models share similar physical designs and frequency ranges, differing only in their specific attenuation characteristics.

Replacement Considerations

Direct substitutes include other LCAT1000 series variants with different attenuation values if the dB requirement changes. Cross-brand replacements must match the SMA male-to-male interface, 50 Ohm impedance, and 6 GHz frequency range.
