LCAT7469-3

Overview

The LCAT7469-3 is a fixed RF attenuator from the L-com Passive series, designed for in-line module applications. It features TNC connectors with a plug-to-jack configuration and maintains a 50 Ohm impedance. The component provides a nominal attenuation of 3 dB with a tolerance of ±1 dB across a frequency range of DC to 12 GHz. It supports a maximum continuous wave power of 2 Watts and exhibits a maximum voltage standing wave ratio (VSWR) of 1.35:1.

Feature Summary

• TNC connectorized design for reliable signal transmission
• Fixed 3 dB attenuation value within specified tolerance
• Operational frequency coverage extending to 12 GHz

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in 50 Ohm communication systems
• Signal conditioning in broadband electronic circuits

Procurement Notes

Verify that the specific part number LCAT7469-3 matches the required 3 dB attenuation value and TNC interface type. Confirm that the manufacturer is L-com and that the device meets the 12 GHz frequency specification. Ensure the procurement documentation explicitly states the 50 Ohm impedance and 2 Watt power rating to avoid substitution errors with other attenuation values or connector types.

Selection Notes

Select this component when a precise 3 dB loss is required at frequencies up to 12 GHz. The TNC interface suits applications needing robust mechanical connections. Consider the 2 Watt power handling limit for high-power environments. Verify that the ±1 dB tolerance aligns with system accuracy requirements. This model is suitable for general-purpose RF attenuation where standard VSWR performance is acceptable.

Part Context

This part belongs to the LCAT7469 series of passive attenuators by L-com. The series includes various attenuation values such as 1 dB, 9 dB, 10 dB, and 20 dB, all sharing similar TNC connectorized designs and frequency ranges. These components are standardized for use in RF systems requiring fixed signal reduction.

Replacement Considerations

Compatible substitutes include other LCAT7469 series models with identical TNC interfaces if different attenuation values are acceptable. Cross-reference datasheets to ensure equivalent frequency range and power handling capabilities before substitution.
