LCAT7468-30

Overview

The LCAT7468-30 is a fixed coaxial attenuator manufactured by L-com, designed for RF signal reduction in high-frequency applications. It provides a nominal attenuation of 30 dB with a 50-ohm impedance rating. 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 into coaxial systems. The unit is rated for a maximum continuous wave power handling of 2 Watts.

Feature Summary

• Provides precise 30 dB signal attenuation for RF circuitry
• Operates effectively within a DC to 12 GHz frequency spectrum
• Utilizes robust brass construction for durability and thermal stability
• Maintains a low Voltage Standing Wave Ratio (VSWR) of 1.35:1

Applications

• RF test and measurement setups requiring signal level reduction
• Protecting sensitive receiver inputs from high-power sources
• Inline attenuation in microwave communication links
• Laboratory environments for signal calibration and testing

Procurement Notes

Verify that the specific order matches the LCAT7468-30 designation to ensure the correct 30 dB attenuation value. Confirm connector orientation requires an N male plug interfacing with an N female jack. Ensure system requirements align with the 2 Watt maximum power handling limit and the 12 GHz upper frequency boundary before procurement.

Selection Notes

Select this component when a fixed 30 dB loss is required between DC and 12 GHz. The N-type interface suits standard coaxial infrastructure. Consider the brass body material for general environmental resilience. Verify that the 1.35:1 VSWR meets the system's reflection tolerance. This model is suitable for applications needing stable attenuation without variable adjustment capabilities.

Part Context

This part belongs to L-com's series of fixed coaxial attenuators, which offer various attenuation values ranging from lower decibel levels up to higher reductions like 30 dB. These components share common design characteristics, including 50-ohm impedance and N-type connectorization. The series supports broadband operation up to 12 GHz, providing consistent performance across multiple RF bands for diverse electronic applications.

Replacement Considerations

Compatible substitutes include other 30 dB fixed attenuators with N male-to-female interfaces and similar power ratings. Ensure replacement units maintain the 12 GHz frequency range and 50-ohm impedance. Verify that alternative models meet or exceed the 1.35:1 VSWR specification to prevent signal integrity issues in existing setups.
