LCAT7094-04

Overview

The LCAT7094-04 is a fixed RF attenuator manufactured by L-com, designed for high-frequency signal management. It provides a precise attenuation value of 4 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range extending from DC to 18 GHz and supports a maximum power handling capacity of 2 Watts. It utilizes N-type connectors, featuring a male-to-female configuration for inline integration. The construction employs passivated stainless steel for the body, ensuring durability and corrosion resistance in demanding environments.

Feature Summary

• Fixed 4 dB attenuation performance
• Wideband operation up to 18 GHz
• Passivated stainless steel housing

Applications

• RF test and measurement setups
• Signal level reduction in communication systems
• Protection of sensitive receiver inputs

Procurement Notes

Verify the specific model suffix against official L-com documentation to confirm the exact attenuation value and connector gender combination. Ensure that the required power rating and frequency range align with system specifications before procurement. Cross-reference the part number with authorized distributors to confirm current availability and authenticity. Check for any updated datasheets that may reflect revised mechanical or electrical tolerances.

Selection Notes

Select this component when a stable 4 dB reduction is required in 50 Ohm systems operating at frequencies up to 18 GHz. Consider the 2 Watt power limit to prevent thermal damage during continuous wave operation. The N-type interface ensures compatibility with standard coaxial infrastructure. Evaluate the need for passivated stainless steel construction if environmental corrosion resistance is a critical design factor.

Part Context

This model belongs to the LCAT7094 series of fixed attenuators from L-com. The series offers various attenuation values while maintaining consistent mechanical and electrical characteristics. These components are engineered for reliable performance in broadband applications. The standardized N-type interface facilitates easy integration into existing RF chains without requiring adapter hardware.

Replacement Considerations

Compatible substitutes include other LCAT7094 variants with different attenuation values, such as LCAT7094-01 or LCAT7094-20, provided the specific dB loss differs. Generic equivalents must match the 50 Ohm impedance, 18 GHz frequency limit, and 2 Watt power rating. Verify connector type and body material compatibility when sourcing third-party replacements.
