LCAT7468-20

Overview

The LCAT7468-20 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in coaxial systems. It provides a nominal attenuation of 20 dB with a 50 Ohm impedance. The device operates across a frequency range from DC to 12 GHz. It features N-type connectors, specifically an N male plug on one end and an N female jack on the other, facilitating inline integration. The unit is rated for a maximum power handling capacity of 2 Watts continuous wave (CW). Key performance metrics include a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1, ensuring minimal signal reflection within its operational bandwidth.

Feature Summary

• Fixed 20 dB attenuation value for precise signal level control
• N-type connector interface with male plug and female jack configuration
• Operational frequency range extending from DC up to 12 GHz
• Brass body construction supporting 2 Watts maximum power rating

Applications

• RF signal path attenuation in communication systems
• Test and measurement equipment requiring precise signal reduction
• Cable assembly integration for impedance matching applications

Procurement Notes

Verify the specific connector gender orientation (N male to N female) matches your system requirements before procurement. Confirm that the 2 Watt power rating and 12 GHz frequency limit are sufficient for your operational environment. Ensure the 50 Ohm impedance aligns with your existing infrastructure to prevent mismatch losses. Check for any specific packaging or datasheet revisions that may affect mechanical dimensions or material specifications.

Selection Notes

Select this component when a fixed 20 dB reduction is required within a 50 Ohm system operating up to 12 GHz. Consider the N-type interface compatibility with your existing cabling and connectors. Evaluate the 2 Watt power handling capability against peak and average signal levels in your application. Compare VSWR specifications to ensure signal integrity meets your system's reflection tolerance limits.

Part Context

This part belongs to the LCAT7468 series of fixed attenuators from L-com, which offers various attenuation values including 4, 5, 6, 9, 10, and 20 dB options. All models in this series share similar physical characteristics, including N-type connectors and a 12 GHz frequency range. The series is designed for consistent performance across different attenuation levels while maintaining standard 50 Ohm impedance and brass construction for durability and thermal stability.

Replacement Considerations

Compatible substitutes include other LCAT7468 series models if different attenuation values are acceptable, such as LCAT7468-10 or LCAT7468-9. Third-party equivalents must match the 20 dB attenuation, 50 Ohm impedance, N-type connector genders, and 12 GHz frequency range. Verify that alternative parts meet the same 2 Watt power rating and 1.35:1 VSWR specifications to ensure functional parity.
