LCAT7469-30

Overview

The LCAT7469-30 is a fixed RF attenuator manufactured by L-com, designed for coaxial signal management. It provides a nominal attenuation of 30 dB with a tolerance of ±5 dB. The component operates within a frequency range from DC to 12 GHz and maintains a characteristic impedance of 50 Ohms. It features TNC connectors, specifically a male plug on one end and a female jack on the other, facilitating in-line module integration. The unit supports a maximum continuous wave power rating of 2 Watts and exhibits a maximum voltage standing wave ratio (VSWR) of 1.35:1.

Feature Summary

• Fixed 30 dB attenuation value for precise signal level reduction
• TNC connector interface with male plug and female jack configuration
• Operational frequency coverage extending from DC up to 12 GHz
• Robust construction suitable for in-line coaxial circuit applications

Applications

• RF signal path attenuation in test and measurement equipment
• Signal conditioning within wireless communication infrastructure
• Impedance matching and noise reduction in microwave circuits

Procurement Notes

Verify the specific datasheet version provided by L-com or authorized distributors to confirm current manufacturing status and detailed mechanical dimensions. Ensure that the TNC connector gender orientation matches the system requirements, as this model specifies a male-to-female configuration. Cross-reference the 30 dB attenuation tolerance and 12 GHz upper frequency limit against application specifications to guarantee performance compliance under operational conditions.

Selection Notes

Select the LCAT7469-30 when a fixed 30 dB loss is required within a 50 Ohm system operating up to 12 GHz. This model is appropriate for applications necessitating TNC connectivity rather than SMA or N-type interfaces. Consider the 2 Watt power handling capability relative to the expected signal levels. Compare against other models in the LCAT7469 series if different attenuation values such as 9 dB are needed while maintaining identical connector types and frequency ranges.

Part Context

This component belongs to the LCAT7469 series of fixed attenuators produced by L-com. The series offers various attenuation values, including 9 dB and 30 dB options, all sharing similar physical characteristics and electrical performance profiles. These devices are engineered for consistent performance across the DC to 12 GHz spectrum, providing reliable signal attenuation solutions for professional RF engineering environments requiring standardized TNC interfaces.

Replacement Considerations

Direct substitutes within the same family include the LCAT7469-9 for lower attenuation requirements. Verify connector compatibility and frequency limits when considering alternative manufacturers' components. Ensure any replacement part matches the 50 Ohm impedance and TNC gender configuration to maintain system integrity without modification.
