LCAT7492-10

Overview

The LCAT7492-10 is a fixed RF attenuator manufactured by L-com, designed for in-line signal reduction applications. It provides a nominal attenuation of 10 dB across a frequency range of 0 Hz to 6 GHz. The component operates with a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 5 Watts. It features a 2.2-5 male connector on one end and a 2.2-5 female connector on the other, facilitating direct integration into coaxial systems.

Feature Summary

• Provides fixed 10 dB signal attenuation for RF circuits
• Operates effectively from DC up to 6 GHz frequency range
• Supports high power handling up to 5 Watts
• Features brass construction with 2.2-5 male-to-female interface

Applications

• RF signal level adjustment in test and measurement equipment
• Attenuation in wireless communication systems operating below 6 GHz
• Signal conditioning in microwave instrumentation setups

Procurement Notes

Verify the specific connector gender configuration (male-to-female) matches your system requirements before procurement. Confirm that the 5-watt power rating aligns with your operational power levels to prevent damage. Ensure the 50-ohm impedance compatibility is maintained throughout the signal chain. Request the official datasheet for precise mechanical dimensions and detailed electrical tolerances prior to finalizing orders.

Selection Notes

Select this model when a fixed 10 dB reduction is required within a 6 GHz bandwidth. Consider the 5-watt power limit for high-power applications. The 2.2-5 interface dictates mating compatibility; ensure adjacent components match these connector types. Brass material offers durability but may require plating considerations for specific environmental conditions compared to stainless steel alternatives.

Part Context

This component belongs to L-com's line of fixed RF attenuators, which offer various attenuation values and power ratings. The LCAT7492 series utilizes robust brass bodies to ensure consistent performance and thermal dissipation. These units are engineered for reliable operation in demanding RF environments where stable attenuation characteristics are critical for system integrity.

Replacement Considerations

Direct substitutes include other L-com models such as LCAT7492-3 or LCAT7492-6 if different attenuation values are needed while maintaining the same form factor and connector type. Third-party equivalents must match the 10 dB value, 50-ohm impedance, 5-watt power rating, and 2.2-5 connector interface to ensure functional interchangeability without circuit modification.
