LCAT7609-1

Overview

The LCAT7609-1 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in radio frequency circuits. It provides an attenuation value of 1dB within a frequency range of 0 Hz to 3 GHz. The component features a 50 Ohm impedance and supports a power handling capacity of 2W. It utilizes TNC connectors configured as an inline module with plug-to-jack interfaces. The unit is constructed with a brass body and is suitable for applications requiring precise signal level adjustment across the specified bandwidth.

Feature Summary

• Provides fixed 1dB attenuation for RF signal management
• Operates effectively from DC up to 3 GHz frequency range
• Features robust 50 Ohm impedance matching for system integration
• Supports 2W power handling capacity for reliable performance

Applications

• RF test and measurement equipment signal conditioning
• Wireless communication systems signal level adjustment
• Laboratory instrumentation input protection
• Broadband circuit design and development

Procurement Notes

Verify the specific part number suffix to confirm the exact attenuation value and connector configuration before ordering. Ensure that the operating frequency and power requirements of the application fall within the component's specified limits of 3 GHz and 2W respectively. Confirm compliance with relevant environmental standards if required for the deployment environment.

Selection Notes

Select this component when a precise 1dB reduction is required in a 50 Ohm system. Consider the TNC interface compatibility with existing cabling and fixtures. Evaluate the thermal management capabilities given the 2W power rating. Compare against other values in the LCAT7609 series if different attenuation levels are needed for the same form factor.

Part Context

This model belongs to the LCA series of fixed attenuators from L-com. The series offers various attenuation values ranging from 1dB to higher dB levels while maintaining consistent physical dimensions and connector types. These components are engineered for durability and consistent performance in demanding RF environments, serving as essential passive elements in signal chain architectures.

Replacement Considerations

Equivalent parts include FMAT7609-1 from Fairview Microwave and PE7609-1 from Pasternack. Verify that substitute components match the 1dB attenuation, 50 Ohm impedance, and TNC connector specifications to ensure seamless integration without re-engineering the host assembly.
