LCAT7468-8

Overview

The LCAT7468-8 is a fixed RF attenuator manufactured by L-com, designed for in-line module applications. It provides an attenuation value of 8dB with a tolerance of ±1 dB. The component operates within a frequency range of DC to 12 GHz and maintains a characteristic impedance of 50 Ohms. It features N-Type connectors, specifically configured as a plug-to-jack interface. The device supports a maximum continuous wave power handling of 2 Watts and exhibits a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1.

Feature Summary

• Fixed 8dB attenuation performance across a wide bandwidth
• N-Type connectorized design for reliable interconnection
• Operates from DC up to 12 GHz frequency range
• Supports 2 Watts maximum continuous wave power

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in 50 Ohm transmission lines
• Signal conditioning in wireless communication systems
• Attenuation stages in high-frequency circuit designs

Procurement Notes

Verify the specific part number suffix against official L-com documentation to confirm exact attenuation values and connector configurations. Ensure that the required frequency range and power handling capabilities align with system specifications before procurement. Cross-reference datasheets for mechanical dimensions and material composition if environmental constraints apply.

Selection Notes

Select this component when a precise 8dB attenuation is required at frequencies up to 12 GHz. Consider the N-Type interface compatibility with existing cabling infrastructure. Evaluate the 2W power rating against peak signal levels to prevent damage. Compare VSWR specifications with system requirements to ensure minimal signal reflection.

Part Context

This model belongs to the LCAT7468 series of fixed attenuators from L-com. The series offers various attenuation values ranging from 1dB to 15dB, all sharing similar electrical characteristics and connector types. These components are standardized for use in 50 Ohm RF environments requiring stable attenuation over a broad bandwidth.

Replacement Considerations

Compatible substitutes include other LCAT7468 series variants such as LCAT7468-7 or LCAT7468-9, provided the specific attenuation difference is acceptable for the application. Ensure any replacement maintains the same N-Type connector configuration and 50 Ohm impedance.
