LCAT7468-4

Overview

The LCAT7468-4 is a fixed RF attenuator manufactured by L-com, designed for in-line signal reduction applications. It provides a nominal attenuation of 4 dB with a tolerance of ±0.5 dB across a frequency range of DC to 12 GHz. The component operates within a 50 Ohm impedance system and supports a maximum continuous wave power handling of 2 Watts. It features N-type connectors, specifically an N male plug on one end and an N female jack on the other, ensuring compatibility with standard coaxial infrastructure. The unit exhibits a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1, indicating efficient signal transmission with minimal reflection.

Feature Summary

• Provides precise 4 dB signal attenuation for RF circuit management
• Operates effectively from DC up to 12 GHz frequency range
• Features robust N-type connector interface for reliable in-line connection
• Supports high power handling capacity suitable for various RF environments

Applications

• RF signal level adjustment in test and measurement setups
• Attenuation in wireless communication systems operating below 12 GHz
• Signal conditioning in radar and electronic warfare equipment
• Integration into microwave subsystems requiring fixed loss components

Procurement Notes

Verify the specific part number LCAT7468-4 against official L-com documentation to confirm the 4 dB attenuation value and N-type connector configuration. Ensure that the required frequency range up to 12 GHz and 2W power rating align with your system design constraints. Cross-reference datasheet specifications for VSWR and impedance matching to guarantee compatibility with existing 50 Ohm infrastructure before procurement.

Selection Notes

Select this component when a fixed 4 dB loss is required within a 50 Ohm system operating up to 12 GHz. Consider the N-type connector interface for mechanical compatibility with standard coaxial cables and adapters. Evaluate the 2W power handling capability against peak and average signal levels in your application. This model is suitable for applications demanding stable attenuation performance without variable adjustment capabilities.

Part Context

The LCAT7468 series comprises a family of fixed attenuators offered by L-com, each providing different attenuation values such as 1 dB, 3 dB, 6 dB, and 9 dB. These components share common design characteristics including N-type connectors, 50 Ohm impedance, and operation up to 12 GHz. The LCAT7468-4 specifically denotes the variant with 4 dB attenuation, fitting into the broader lineup of precision RF passive components designed for consistent performance in high-frequency applications.

Replacement Considerations

Direct substitutes include other LCAT7468 series models if different attenuation values are acceptable, such as LCAT7468-3 or LCAT7468-6. Third-party equivalents must match the 4 dB attenuation, 50 Ohm impedance, DC-12 GHz frequency range, and N-type connector interface. Verify power handling and VSWR specifications to ensure equivalent performance in critical RF paths.
