LCAT7094-40

Overview

The LCAT7094-40 is a fixed RF attenuator manufactured by L-com, designed for high-frequency signal management. It provides a precise attenuation value of 40 dB across a frequency range extending from DC to 18 GHz. The component is rated for an input power handling capacity of 2 Watts and maintains a characteristic impedance of 50 Ohms. It features a robust coaxial interface configuration utilizing N-type connectors, specifically connecting an N-male plug to an N-female jack. The housing is constructed from stainless steel with passivation treatment to ensure durability and environmental resistance in demanding operational settings.

Feature Summary

• Provides fixed 40 dB signal reduction capability within the specified frequency band
• Utilizes durable stainless steel construction with passivated surface treatment
• Supports standard N-type male-to-female coaxial interconnection

Applications

• RF signal level adjustment in microwave test and measurement equipment
• Attenuation insertion in wireless communication base station architectures
• Signal conditioning within radar system transmission and reception chains

Procurement Notes

Verify that the specific order matches the LCAT7094-40 designation to ensure the correct 40 dB attenuation value. Confirm compatibility with existing N-type connector interfaces on both source and load sides. Ensure the application environment does not exceed the 2 Watt maximum power rating or the 18 GHz upper frequency limit. Check for required passivation specifications if operating in corrosive conditions.

Selection Notes

Select this component when a fixed 40 dB reduction is required at frequencies up to 18 GHz. Consider the 2 Watt power handling capability relative to the expected signal levels. Evaluate the mechanical fit of the N-type connectors against the system's physical interface requirements. Compare against other models in the series, such as LCAT7094-02 or LCAT7094-08, if different attenuation values better suit the circuit design needs.

Part Context

This model belongs to L-com's LCAT7094 series of fixed attenuators. The series offers various attenuation steps, including 2 dB, 8 dB, and others, all sharing similar electrical characteristics and form factors. These components are engineered for consistent performance across wide bandwidths, providing reliable signal control for professional RF applications requiring standardized connector interfaces and robust physical construction.

Replacement Considerations

Direct substitutes include other LCAT7094 series variants like LCAT7094-02 or LCAT7094-08 only if the specific attenuation value differs but the interface and power ratings remain compatible. Cross-brand replacements must match the 50 Ohm impedance, N-type connector gender, 2W power rating, and 18 GHz frequency response to maintain system integrity.
