LCAT1003-09

Overview

The LCAT1003-09 is an RF fixed attenuator manufactured by L-com, designed for signal reduction in radio frequency circuits. It provides a nominal attenuation of 9 dB with an accuracy of ±0.4 dB across a frequency range from DC to 3 GHz. The component features N-type male and female connectors, ensuring compatibility with standard coaxial systems. It supports a maximum input power of 2 Watts and operates within a temperature range of -55°C to +125°C. The voltage standing wave ratio (VSWR) is maintained below 1.20, and the system impedance is 50 Ohms.

Feature Summary

• Provides precise 9 dB signal attenuation for RF applications
• Operates effectively from DC up to 3 GHz frequency range
• Features robust N-type male-to-female connector interface
• Supports high power handling up to 2 Watts

Applications

• RF test and measurement setups requiring signal reduction
• Wireless communication systems for level adjustment
• Broadband network infrastructure components
• Laboratory equipment calibration and testing

Procurement Notes

Verify the specific datasheet revision and connector gender configuration before ordering. Confirm that the operating environment temperature falls within the specified -55°C to +125°C range. Ensure the application power levels do not exceed the 2W maximum rating. Check for availability constraints as supply status may vary by region. Validate impedance matching requirements for the 50 Ohm system integration.

Selection Notes

Select this model when a fixed 9 dB attenuation is required between DC and 3 GHz. Choose based on the need for N-type connectors for robust mechanical connection. Consider the 2W power rating for moderate signal levels. Evaluate the VSWR specification for minimal reflection in sensitive RF paths. Compare against other attenuation values if signal reduction needs differ.

Part Context

This component belongs to L-com's passive RF attenuator series, specifically the LCAT1003 line. These devices are engineered for reliable performance in demanding RF environments. The series offers various attenuation values and connector types to suit different system architectures. The LCAT1003-09 specifically addresses the need for 9 dB reduction with N-type interfaces.

Replacement Considerations

Direct substitutes include other LCAT1003 series variants with different attenuation values but identical connectors. Cross-reference with other manufacturers' 9dB N-type attenuators rated for DC-3GHz and 2W. Verify that any replacement matches the physical dimensions and mounting requirements. Ensure electrical specifications such as VSWR and power handling are equivalent or superior.
