LCAT7468-15

Overview

The LCAT7468-15 is a fixed RF attenuator manufactured by L-com, providing a nominal attenuation of 15 dB. It operates within a frequency range from DC to 12 GHz and is designed for 50 Ohm impedance systems. The device utilizes N-type connectors, featuring an N male (plug) on one end and an N female (jack) on the other, facilitating in-line integration into coaxial cable assemblies. It is rated for a maximum power handling capacity of 2 Watts continuous wave. The unit maintains a maximum voltage standing wave ratio (VSWR) of 1.35:1 and typically exhibits an attenuation tolerance of ±1 dB.

Feature Summary

• Provides precise 15 dB signal reduction across a wide bandwidth up to 12 GHz
• Features robust brass construction for durability and thermal stability
• Utilizes standard N-type male-to-female interface for versatile connectivity
• Maintains low VSWR to ensure minimal signal reflection during operation

Applications

• RF test and measurement setups requiring specific signal level adjustments
• Telecommunications infrastructure equipment interfacing
• Wireless communication system component integration
• Laboratory benchtop instrumentation signal conditioning

Procurement Notes

Verify that the required attenuation value matches the application needs, as this model provides a fixed 15 dB loss. Confirm connector orientation requirements, specifically the N male to N female configuration, to ensure compatibility with existing cabling. Check power rating constraints against peak signal levels to prevent damage. Ensure frequency coverage up to 12 GHz aligns with operational bandwidth. Source from authorized distributors to guarantee authenticity and datasheet compliance.

Selection Notes

Select this component when a fixed 15 dB attenuation is necessary within a 50 Ohm system operating below 12 GHz. Consider the N-type connector interface for compatibility with standard coaxial hardware. Evaluate the 2 Watt power rating against maximum expected signal levels. Compare VSWR specifications if signal integrity is critical. This model is suitable for applications requiring stable, non-adjustable signal reduction without active components.

Part Context

The LCAT7468-15 belongs to the LCAT7468 series of fixed attenuators from L-com. This series offers various attenuation values, including 3, 5, 8, 9, and 15 dB options, all sharing similar physical and electrical characteristics such as the N-type connector interface and 12 GHz frequency range. These components are designed for consistent performance in high-frequency environments.

Replacement Considerations

Compatible substitutes include other LCAT7468 models with different attenuation values if the specific 15 dB requirement can be adjusted. Cross-reference with other manufacturers offering 15 dB fixed attenuators with N-type connectors and 12 GHz capability, ensuring matching impedance, power ratings, and VSWR specifications.
