LCAT7094-12

Overview

The LCAT7094-12 is a fixed RF attenuator manufactured by L-com, designed for high-frequency signal management. It provides a precise attenuation value of 12 dB across a broad operational frequency range extending from 0 Hz to 18 GHz. The component is rated for a maximum power handling capacity of 2 Watts and maintains a characteristic impedance of 50 Ohms. It features N-Type connectors, specifically configured as an in-line module with male-to-female interfaces. The housing is constructed from passivated stainless steel, ensuring durability and environmental resistance suitable for demanding RF applications.

Feature Summary

• Provides fixed 12 dB signal attenuation for consistent RF circuit performance
• Operates effectively from DC up to 18 GHz frequency range
• Handles continuous power loads up to 2 Watts
• Features robust passivated stainless steel construction for environmental protection

Applications

• RF signal level adjustment in communication systems
• Impedance matching and reflection reduction in test and measurement setups
• Signal conditioning in microwave and millimeter-wave circuits
• Integration into coaxial cable assemblies requiring specific loss characteristics

Procurement Notes

Verify the part number suffix matches the required attenuation value, as the series includes various dB ratings. Confirm connector gender configuration (N Male to N Female) aligns with system interface requirements. Ensure the 2W power rating and 18 GHz frequency limit meet application specifications. Check for passivated stainless steel housing if environmental durability is critical. Validate that the 50 Ohm impedance matches the surrounding circuitry to prevent signal reflections.

Selection Notes

Select this model when a fixed 12 dB loss is required within an 18 GHz bandwidth. Consider the 2W power handling capability for moderate signal levels. The N-Type interface dictates compatibility with standard coaxial systems. Stainless steel construction offers advantages over brass or aluminum in corrosive environments. Compare against other series models if higher power or different connector types are needed.

Part Context

This component belongs to L-com's LCAT7094 series of fixed attenuators. The series offers various attenuation values ranging from 1 dB to 40 dB, all sharing similar physical and electrical characteristics. These devices are standardized for use in general RF infrastructure, providing reliable signal reduction without active components. The series is known for its wideband performance and rugged mechanical design.

Replacement Considerations

Direct substitutes include other LCAT7094 variants with identical form factors but different attenuation values, such as LCAT7094-10 or LCAT7094-15, if the loss requirement changes. Cross-manufacturer replacements must match the 12 dB value, 50 Ohm impedance, N-Type connectors, and 18 GHz frequency range. Verify power handling capabilities and physical dimensions before substitution.
