LCAT7469-20

Overview

The LCAT7469-20 is a 20 dB fixed attenuator from L-com, designed for RF applications operating from DC to 12 GHz. It features a 50 Ohm impedance and utilizes TNC male (plug) to TNC female (jack) connectors in an inline module configuration. The component supports a maximum power dissipation of 2 Watts (CW). This versatile coaxial package ensures reliable signal attenuation across the specified frequency range.

Feature Summary

• Provides precise 20 dB signal attenuation within a robust coaxial design
• Operates effectively from DC up to 12 GHz frequency range
• Connects via standard TNC male plug to TNC female jack interface

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching between high-power sources and sensitive receivers
• Signal conditioning in broadband communication systems

Procurement Notes

Verify that the required attenuation value is exactly 20 dB and the frequency range extends to at least 12 GHz. Confirm the connector gender combination matches the system requirements: TNC male plug on one end and TNC female jack on the other. Ensure the 50 Ohm impedance aligns with the circuit design. Check that the 2 Watt CW power rating is sufficient for the intended application environment.

Selection Notes

Select this model when a fixed 20 dB loss is required for frequencies up to 12 GHz. The TNC interface offers a secure connection suitable for moderate performance needs. Consider the 2 Watt power handling capability relative to the source output. This inline module format allows for easy integration into existing coaxial cable runs without requiring additional adapters.

Part Context

This component belongs to L-com's series of fixed attenuators, which offer various attenuation levels and frequency ranges. The LCAT7469 series specifically utilizes TNC connectors, providing a balance of performance and ease of use. These attenuators are designed to maintain consistent impedance and minimize reflections across their operational bandwidth.

Replacement Considerations

Equivalent parts include FMAT7469-20, PE7469-20, and R414503000. Verify that substitutes match the 20 dB attenuation, 12 GHz frequency limit, 50 Ohm impedance, and TNC connector types before implementation.
