LCAT7467-10

Overview

The LCAT7467-10 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in high-frequency applications. It provides a nominal attenuation of 10 dB with a frequency range extending from 0 Hz to 12 GHz. The device operates within a 50 Ohm impedance system and utilizes SMA connectors, specifically featuring an SMA male plug on one end and an SMA female jack on the other. This configuration allows for direct in-line integration into coaxial cable assemblies or test setups without requiring additional adapters.

Feature Summary

• Provides precise 10 dB signal attenuation across a wide DC to 12 GHz bandwidth
• Features robust SMA male-to-female connector interface for secure in-line mounting
• Maintains consistent 50 Ohm impedance matching throughout the operational frequency range

Applications

• RF signal level adjustment in measurement and test equipment
• Protection of sensitive receiver inputs from high-power signals
• Integration into microwave and millimeter-wave circuit designs

Procurement Notes

Verify that the specific part number LCAT7467-10 matches the required 10 dB attenuation value and SMA connector polarity. Confirm that the 12 GHz maximum frequency rating aligns with your application's spectral requirements. Ensure the 50 Ohm impedance specification is compatible with your existing transmission line infrastructure to prevent signal reflection issues during procurement.

Selection Notes

Select this component when a fixed 10 dB reduction is necessary within a 50 Ohm system operating up to 12 GHz. The SMA interface is suitable for standard coaxial connections. Consider power handling capabilities if the input signal exceeds typical ratings, as datasheet specifics on maximum continuous power should be reviewed against the actual signal levels present in the target circuit environment.

Part Context

This model belongs to the LCAT7467 series of fixed attenuators from L-com, which offers various attenuation values such as 3, 6, 8, 15, 20, and 30 dB. All units in this series share similar physical characteristics, including the SMA male-to-female configuration and a common 12 GHz frequency limit. The series provides standardized solutions for signal conditioning across different attenuation needs while maintaining uniform connector types for ease of integration.

Replacement Considerations

Compatible substitutes include other LCAT7467 variants with identical connector types but different attenuation values, provided the specific dB loss requirement changes. External manufacturers offering SMA fixed attenuators must match the 10 dB nominal loss, 50 Ohm impedance, and 12 GHz upper frequency limit to ensure functional equivalence.
