LCAT1006-03

Overview

The LCAT1006-03 is a fixed RF attenuator manufactured by L-Com, designed for signal reduction in high-frequency applications. It operates within a frequency range of 0 Hz to 18 GHz and provides a nominal attenuation of 3 dB. The component features SMA male-to-female connectors and maintains a 50 Ohm impedance. It supports a maximum power rating of 2 W with a Voltage Standing Wave Ratio (VSWR) of 1.35:1. The unit is constructed from gold-plated brass and functions reliably within an operating temperature range of -55°C to +125°C.

Feature Summary

• Gold-plated brass housing for corrosion resistance and durability
• SMA male to female inline connector configuration
• Wideband operation extending from DC to 18 GHz

Applications

• RF test and measurement equipment
• Wireless communication systems
• Signal conditioning in microwave circuits

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm the 3 dB attenuation value and SMA gender configuration. Ensure compatibility with system impedance requirements of 50 Ohms. Confirm that the 2 W power handling capacity meets the operational demands of the intended circuit environment before finalizing procurement decisions.

Selection Notes

Select this component when a precise 3 dB signal reduction is required across a broad bandwidth up to 18 GHz. The SMA interface ensures standard connectivity, while the robust thermal design supports operation in extreme temperatures. Consider the physical dimensions and mounting style if space constraints exist within the assembly layout.

Part Context

This device belongs to the L-Com passive RF attenuator series, which offers various attenuation values and connector types. These components are engineered for consistent performance in demanding radio frequency environments. The series utilizes precision internal structures to maintain low VSWR and stable attenuation characteristics over the specified frequency range.

Replacement Considerations

Compatible substitutes include other 3 dB SMA fixed attenuators from manufacturers such as Mini-Circuits or Pasternack, provided they match the 0-18 GHz frequency range, 50 Ohm impedance, and 2 W power rating specifications.
