LCAT7491-6

Overview

The LCAT7491-6 is a fixed RF attenuator manufactured by L-com, designed for high-power applications up to 10W. It provides a precise attenuation value of 6dB across a frequency range extending from 0 Hz to 6 GHz. The component utilizes NEX10 connectors, featuring a male-to-female configuration for inline integration. Constructed with an aluminum body, it ensures thermal stability and mechanical durability in demanding RF environments.

Feature Summary

• Provides fixed 6dB signal reduction for RF systems
• Supports continuous power handling up to 10 watts
• Operates effectively within a 0 Hz to 6 GHz bandwidth
• Features robust NEX10 male-to-female connector interface

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• High-power transmitter line protection
• Antenna system impedance matching networks

Procurement Notes

Verify the specific connector gender configuration (male-to-female) against system requirements before ordering. Confirm that the 10W power rating aligns with peak operational loads. Ensure the NEX10 interface compatibility matches existing cabling infrastructure. Request official datasheets to validate frequency response characteristics for critical 6GHz applications.

Selection Notes

Choose this model when a fixed 6dB attenuation is required for high-power signals up to 10W. The NEX10 interface suits applications needing robust connections over standard N-type. Consider the 6GHz upper frequency limit for broadband usage. Aluminum construction offers advantages for heat dissipation in continuous wave operations compared to lower-rated components.

Part Context

This part belongs to the LCAT7491 series of fixed attenuators from L-com. The series includes variants with different attenuation values such as 3dB, 10dB, and 20dB, all sharing similar power handling and frequency specifications. These components are standardized for use in professional RF infrastructure requiring reliable signal management.

Replacement Considerations

Compatible substitutes include other LCAT7491 series models like LCAT7491-3 or LCAT7491-10 if different attenuation levels are acceptable. Cross-brand replacements must match the 10W power rating, 6GHz frequency range, and NEX10 connector type to ensure functional equivalence.
