LCAT7469-6

Overview

The L-com LCAT7469-6 is a fixed attenuator designed for RF applications operating within a DC to 12 GHz frequency range. It provides a nominal attenuation of 6 dB with a tolerance of ±1 dB. The component features TNC connectors, specifically a male plug on one end and a female jack on the other, ensuring compatibility with standard coaxial systems. Rated for a maximum power handling of 2 Watts continuous wave (CW), it maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1. Constructed as a 50-ohm device, it supports signal conditioning in high-frequency environments requiring precise impedance matching.

Feature Summary

• Fixed 6 dB attenuation value for consistent signal reduction
• Operates across a wide DC to 12 GHz frequency spectrum
• TNC connectorized design with male plug and female jack configuration
• Maintains low VSWR for effective impedance matching

Applications

• RF signal testing and measurement setups
• Attenuating signals in communication systems
• Protecting sensitive receiver inputs from high power levels
• Impedance matching in coaxial cable networks

Procurement Notes

Verify the specific part number LCAT7469-6 against official L-com documentation to confirm the 6 dB attenuation rating and TNC connector type. Ensure the application environment does not exceed the 2 Watt CW power limit or the 12 GHz frequency range. Check for any ordering suffixes that might indicate variant specifications, although standard listings typically denote the base model. Confirm lead times and availability through authorized distributors.

Selection Notes

Select this component when a fixed 6 dB reduction is required within a 50-ohm system up to 12 GHz. The TNC interface is suitable for applications requiring robust mechanical connections. Consider the 2 Watt power rating to ensure safe operation under continuous wave conditions. Compare with other models in the LCAT7469 series if different attenuation values such as 3 dB, 9 dB, or 20 dB are needed for alternative circuit requirements.

Part Context

The LCAT7469-6 belongs to the LCAT7469 series of fixed attenuators manufactured by L-com. This series offers various attenuation values including 3 dB, 9 dB, and 20 dB options, all sharing similar electrical characteristics and connector types. These components are designed for reliable performance in RF circuits, providing consistent signal attenuation without introducing significant reflection due to their low VSWR specifications.

Replacement Considerations

Direct substitutes within the same series include LCAT7469-3, LCAT7469-9, and LCAT7469-20, which offer different attenuation values but share identical connector types and frequency ranges. Cross-brand replacements must match the 50-ohm impedance, TNC interface, and 12 GHz frequency capability.
