LCAT7468-5

Overview

The LCAT7468-5 is a fixed RF attenuator manufactured by L-com, designed for in-line coaxial applications. It provides a nominal attenuation of 5 dB with a tolerance of ±0.5 dB across a frequency range from DC to 12 GHz. The component features N-type connectors, specifically an N male (plug) to N female (jack) configuration, ensuring compatibility with standard coaxial systems. It operates at a characteristic impedance of 50 Ohms and supports a maximum continuous wave power rating of 2 Watts. The unit maintains a maximum voltage standing wave ratio (VSWR) of 1.35:1, ensuring minimal signal reflection within its specified operational bandwidth.

Feature Summary

• Provides precise 5 dB signal attenuation for RF circuitry
• Operates effectively from DC up to 12 GHz frequency range
• Utilizes robust N-type male-to-female connector interface
• Supports high power handling with 2 Watt CW rating

Applications

• RF signal level adjustment in test and measurement equipment
• Attenuation insertion in microwave communication systems
• Protection of sensitive receiver inputs in radio frequency setups
• Calibration and testing of RF components and subsystems

Procurement Notes

Verify the specific part number LCAT7468-5 against manufacturer datasheets to confirm the 5 dB attenuation value and N-type connector orientation. Ensure that the required frequency range up to 12 GHz and 2W power rating align with system requirements. Cross-reference connector gender specifications to guarantee correct mating with existing N-type cable assemblies or adapters in the intended application environment.

Selection Notes

Select this component when a fixed 5 dB reduction is required within a 50 Ohm system operating up to 12 GHz. Consider the N-type interface for mechanical durability and wideband performance. Evaluate the 2W power limit against peak and average signal levels to prevent thermal damage. This model is suitable for applications demanding stable attenuation characteristics without variable adjustment capabilities.

Part Context

The LCAT7468-5 belongs to L-com's series of fixed coaxial attenuators, which offer various attenuation values such as 6 dB, 8 dB, and 9 dB. These components are engineered for consistent performance in RF environments. The series utilizes standardized N-type connectors to facilitate easy integration into existing coaxial infrastructure, providing reliable signal management solutions for professional audio, video, and telecommunications applications.

Replacement Considerations

Compatible substitutes include other 5 dB fixed attenuators with N-type connectors and similar frequency/power ratings. Verify that alternative parts match the 50 Ohm impedance and 12 GHz upper frequency limit. Ensure connector genders (male-to-female) are identical to maintain physical connectivity. Check if replacement units meet the same VSWR and power handling specifications to avoid performance degradation.
