LCAT7396-3

Overview

The LCAT7396-3 is a fixed RF attenuator manufactured by L-com, designed for use in coaxial cable systems. It provides a nominal attenuation of 3 dB with a tolerance of ±0.5 dB. The component operates within a frequency range of DC to 3 GHz and features a characteristic impedance of 75 Ohms. It supports a maximum power handling capacity of 2 Watts continuous wave (CW). The device utilizes F-type connectors, specifically configured as an inline module with male-to-female connections. Voltage Standing Wave Ratio (VSWR) is maintained below 1.3:1.

Feature Summary

• Provides precise 3 dB signal attenuation for RF applications
• Operates effectively from DC up to 3 GHz frequency range
• Constructed with 75 Ohm impedance matching for video and broadcast systems
• Features durable F-type male to female inline connector interface

Applications

• RF signal level adjustment in broadcast transmission lines
• Attenuation requirements in 75 Ohm coaxial cable networks
• Signal conditioning in video distribution systems
• Test and measurement setups requiring fixed attenuation

Procurement Notes

Verify the specific part number LCAT7396-3 against manufacturer documentation to ensure correct attenuation value and connector type. Confirm that the 75 Ohm impedance and F-type connectors match system requirements. Check for any updated datasheets or revision history from L-com prior to ordering to guarantee compliance with current specifications.

Selection Notes

Select this component when a fixed 3 dB reduction is required in a 75 Ohm environment. Ensure the operating frequency does not exceed 3 GHz. Verify that the power handling capability of 2 Watts CW is sufficient for the application. Consider the physical size and mounting style if space constraints exist within the equipment chassis.

Part Context

This model belongs to L-com's series of fixed attenuators designed for coaxial applications. The series includes variants with different attenuation values, such as 4 dB and 7 dB models, all sharing similar construction standards. These components are engineered to meet industry specifications for reliability and performance in RF environments.

Replacement Considerations

Direct substitutes may include other L-com models within the same series offering identical 3 dB attenuation and 75 Ohm impedance. Verify connector compatibility and frequency response before swapping with generic equivalents. Ensure any replacement maintains the 2W power rating and VSWR specifications.
