LCAT1003-07

Overview

The LCAT1003-07 is a fixed RF attenuator manufactured by L-com. It provides a nominal attenuation value of 7 dB across a frequency range of 0 Hz to 3 GHz. The component features N-type connectors, specifically a male-to-female configuration, ensuring compatibility with standard coaxial systems. It operates at an impedance of 50 Ohms and supports a maximum power handling capacity of 2 Watts. The device is designed as a inline module for signal level adjustment in radio frequency applications.

Feature Summary

• Provides precise 7 dB signal attenuation within the 0 Hz to 3 GHz operational bandwidth
• Utilizes robust N-type male to female connector interface for secure inline integration
• Engineered to handle up to 2 Watts of continuous RF power at 50 Ohm impedance

Applications

• RF instrument calibration requiring specific signal reduction levels
• Signal source output attenuation to prevent overload in downstream components
• Power balancing in multi-channel RF distribution systems

Procurement Notes

Verify that the required attenuation value matches the 7 dB specification exactly, as other models in the series offer different values such as 2 dB or 4 dB. Confirm that the operating frequency does not exceed the 3 GHz upper limit and that the system power remains within the 2 Watt rating. Ensure the N-type connector gender aligns with the existing cable assembly to maintain proper male-to-female connectivity.

Selection Notes

Select this model when a fixed 7 dB reduction is necessary for frequencies up to 3 GHz. Consider the 2 Watt power limit when designing for high-power transmission lines. The N-type interface dictates compatibility with standard industrial and telecom coaxial cabling. Choose alternative attenuation values from the same series if the signal strength requirements differ from the 7 dB target.

Part Context

This component belongs to L-com's line of fixed RF attenuators designed for inline signal management. These devices are typically used to protect sensitive equipment from excessive input power or to match impedance levels between stages. The series includes various attenuation values while maintaining consistent connector types and power ratings for standardized system integration.

Replacement Considerations

Direct substitutes include other LCAT1003 series variants with identical N-type interfaces but different attenuation values, such as LCAT1003-04 (4 dB) or LCAT1003-02 (2 dB), provided the specific dB requirement can be adjusted. Cross-manufacturer replacements must match the 50 Ohm impedance, 3 GHz frequency range, and 2 Watt power handling capabilities.
