LCAT1000-03

Overview

The LCAT1000-03 is a fixed RF attenuator manufactured by L-com, designed for coaxial inline applications. It provides a nominal attenuation of 3 dB with a frequency range extending from 0 Hz to 6 GHz. The component operates at a maximum power rating of 2 W and maintains a characteristic impedance of 50 Ohms. It features SMA male connectors on both ends and utilizes a stainless steel body with an integrated hex nut for secure installation.

Feature Summary

• Coaxial inline design with SMA male-to-male connectivity
• Stainless steel housing with hex nut for mechanical stability
• Fixed 3 dB attenuation performance across DC to 6 GHz

Applications

• RF signal level adjustment in test and measurement setups
• Impedance matching in 50 Ohm transmission lines
• Signal protection in wireless communication systems

Procurement Notes

Verify the specific connector gender configuration, as product descriptions may vary between male-to-female and male-to-male variants. Confirm the frequency range and power handling requirements against your system specifications. Ensure compatibility with SMA interface standards before integration into existing RF infrastructure.

Selection Notes

Select this model when a fixed 3 dB reduction is required within the 6 GHz bandwidth. Consider the physical dimensions and hex nut mounting style for panel or rack integration. Verify that the 2 W power rating meets the peak and average power demands of the application environment.

Part Context

This component belongs to the LCAT1000 series of passive RF attenuators from L-com. The series offers various attenuation values while maintaining consistent 50 Ohm impedance and 2 W power handling capabilities across different frequency ranges.

Replacement Considerations

Equivalent parts include ATT-0313-07-BNC-10, PE7437-7, and R414407000. Note that these substitutes may feature different connector types such as BNC, requiring adapter solutions or circuit redesigns for direct replacement.
