LCAT7469-15

Overview

The LCAT7469-15 is a fixed coaxial attenuator manufactured by L-com, designed for RF signal management within high-frequency systems. It provides a precise attenuation value of 15 dB with a tolerance of ±1 dB, ensuring consistent signal reduction across operational bands. The component operates effectively from DC to 12 GHz, supporting applications requiring stable performance in wideband environments. It features a maximum continuous wave power rating of 2 Watts and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1, indicating low signal reflection. The device utilizes a 50 Ohm impedance system, compatible with standard RF infrastructure.

Feature Summary

• Provides fixed 15 dB signal attenuation with ±1 dB tolerance
• Operates across a frequency range from DC to 12 GHz
• Supports up to 2 Watts continuous wave power handling
• Maintains a maximum VSWR of 1.35:1 for minimal reflection

Applications

• RF test and measurement equipment signal conditioning
• Wireless communication system power level adjustment
• Satellite navigation receiver input protection
• Laboratory benchtop instrumentation signal scaling

Procurement Notes

Verify the specific connector configuration matches the required TNC male-to-female interface before integration. Confirm that the 15 dB attenuation value aligns with the target signal loss requirements for the specific circuit design. Ensure the operating environment remains within the specified 2 Watt power limit to prevent thermal damage or performance degradation during continuous operation.

Selection Notes

Select this model when a precise 15 dB reduction is required within the 12 GHz bandwidth. Consider the TNC connector type for secure mating in vibration-prone environments compared to SMA alternatives. Evaluate the 2 Watt power rating against peak signal levels to ensure adequate headroom. Compare VSWR specifications with other attenuators if strict impedance matching is critical for the application's signal integrity.

Part Context

This component belongs to L-com's series of passive coaxial attenuators, specifically designed for inline signal management. It complements other models in the family offering different attenuation values while maintaining similar electrical characteristics and connector styles. The product line supports various RF frequencies and power levels, providing standardized solutions for signal attenuation needs across diverse electronic systems.

Replacement Considerations

Direct substitutes include other L-com fixed attenuators with identical 15 dB attenuation and TNC connectors, such as variants within the same LCAT7469 series. Cross-manufacturer replacements must match the 50 Ohm impedance, 12 GHz frequency limit, and 2 Watt power rating. Verify connector gender and thread compatibility to ensure mechanical interchangeability without adapter usage.
