LCAT7467-15

Overview

The LCAT7467-15 is a fixed RF attenuator manufactured by L-com, designed for signal level reduction in high-frequency applications. It provides a nominal attenuation of 15 dB with a tolerance of ±1 dB across a frequency range from DC to 12 GHz. The component features SMA connectors, specifically an SMA male plug to SMA female jack configuration, ensuring compatibility with standard coaxial systems. It operates at a 50 Ohm impedance and supports a maximum continuous wave power of 2 Watts. The device maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1, indicating efficient signal transmission with minimal reflection within its specified operational bandwidth.

Feature Summary

• Fixed 15 dB attenuation value with precise tolerance control
• Wideband operation spanning from DC up to 12 GHz
• SMA connectorized design for direct cable integration
• High power handling capability of 2 Watts continuous wave

Applications

• RF test and measurement setups requiring precise signal reduction
• Communication systems needing signal level adjustment between components
• Antenna feed lines for impedance matching and power management
• Laboratory equipment for attenuating high-frequency signals

Procurement Notes

Verify the specific datasheet version provided by L-com or authorized distributors to confirm current manufacturing status and detailed electrical specifications. Ensure that the SMA connector gender and mating requirements align with existing system infrastructure. Cross-reference part numbers to distinguish between similar models in the LCAT7467 series, which may vary in attenuation values but share identical physical and frequency characteristics. Confirm environmental ratings if deployment involves extreme temperatures or harsh conditions.

Selection Notes

Select this model when a fixed 15 dB reduction is required within a 50 Ohm system operating up to 12 GHz. Consider the 2 Watt power rating to ensure it exceeds the maximum expected signal power in the application path. The SMA interface dictates compatibility; verify that mating connectors are available or that adapters are not needed to avoid additional insertion loss. Compare against variable attenuators if adjustable levels are anticipated, though fixed types offer superior stability and lower cost for static configurations.

Part Context

This component belongs to the LCAT7467 series of fixed attenuators from L-com, which offers various attenuation steps such as 5 dB, 8 dB, and 20 dB. All models in this series share common design parameters including the DC to 12 GHz frequency range, 50 Ohm impedance, and SMA connectorization. The series is engineered for consistent performance in RF environments, providing reliable signal attenuation without introducing significant distortion or reflection.

Replacement Considerations

Direct substitutes include other LCAT7467 variants with different attenuation values if the specific 15 dB requirement can be adjusted. Generic replacements must match the 50 Ohm impedance, SMA plug-to-jack configuration, and 12 GHz upper frequency limit. Verify that alternative manufacturers' parts meet the same VSWR and power handling specifications to maintain system integrity.
