LCAT7609-20

Overview

The LCAT7609-20 is a fixed RF attenuator manufactured by L-com, designed for high-frequency signal management. It provides an attenuation value of 20 dB with a characteristic impedance of 50 Ohms. The device operates within a frequency range from DC to 3 GHz and supports a maximum power handling capacity of 2 Watts. It utilizes TNC connectors in a male-to-female configuration, forming an inline module suitable for precise signal level reduction in RF systems.

Feature Summary

• Provides fixed 20 dB attenuation for consistent signal level control
• Operates effectively across a broad spectrum from DC to 3 GHz
• Features robust brass body construction for durability
• Utilizes standard TNC male-to-female interface for easy integration

Applications

• RF signal path attenuation in communication systems
• Test and measurement equipment requiring precise signal reduction
• Wireless infrastructure components operating up to 3 GHz
• Circuit protection by reducing input power levels

Procurement Notes

Verify the specific connector gender configuration matches the system requirements before ordering. Confirm that the 2 Watt power rating aligns with the operational power levels of the application. Ensure the 50 Ohm impedance is compatible with the surrounding circuitry to prevent signal reflections. Check for any environmental specifications if the component will be used in extreme conditions.

Selection Notes

Select this model when a fixed 20 dB reduction is required at frequencies up to 3 GHz. Consider the 2 Watt power handling capability to ensure reliability under load. The TNC interface dictates compatibility with existing cable assemblies. Compare against other series if different attenuation values or connector types are needed for the specific design constraints.

Part Context

This component belongs to the LCAT series of fixed attenuators from L-com. It shares the same physical form factor and connector style as other variants in the line, such as the LCAT7609-3, differing primarily in its attenuation value. The series is designed for general-purpose RF applications requiring reliable signal attenuation without variable adjustment capabilities.
