LCAT7609-40

Overview

The LCAT7609-40 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in coaxial systems. It provides an attenuation value of 40 dB with a nominal impedance of 50 Ohms. The device operates within a frequency range from DC to 3 GHz and handles a maximum power rating of 2 Watts. It features a TNC male to TNC female connector configuration, ensuring compatibility with standard coaxial interfaces.

Feature Summary

• Provides precise 40 dB signal attenuation for RF applications
• Operates reliably across a frequency spectrum from DC to 3 GHz
• Supports continuous power loads up to 2 Watts
• Utilizes durable brass construction with TNC male-to-female connectivity

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• Antenna system impedance matching and protection
• Circuit board input/output signal conditioning

Procurement Notes

Verify the specific manufacturer part number LCAT7609-40 against official L-com documentation to ensure authenticity. Confirm that the required attenuation value of 40 dB and power rating of 2 Watts align with your system design requirements. Check connector orientation (TNC male to female) to guarantee physical compatibility with existing cabling infrastructure before finalizing procurement.

Selection Notes

Select this component when a high attenuation value of 40 dB is required within a 50 Ohm system. Ensure the operating frequency does not exceed 3 GHz and that the signal power remains below 2 Watts to prevent damage. This model is suitable for applications requiring robust brass construction and standard TNC interface connections for reliable RF performance.

Part Context

This component belongs to the LCAT7609 series of fixed attenuators from L-com, which offers various attenuation values such as 3 dB and 20 dB. These devices are engineered for consistent performance in RF environments, providing stable impedance and low VSWR characteristics essential for maintaining signal integrity in coaxial transmission lines.

Replacement Considerations

Compatible substitutes include other 40 dB fixed attenuators with identical TNC male-to-female configurations and 50 Ohm impedance. Ensure replacement units support the same 2 Watt power rating and DC to 3 GHz frequency range to maintain system functionality without modification.
