LCAT1005-05

Overview

The LCAT1005-05 is an RF fixed attenuator manufactured by L-com, designed for signal reduction in radio frequency circuits. It provides a precise attenuation value of 5 dB across a frequency range from DC to 18 GHz. The component features a 50 Ohm impedance and supports an input power rating of 2 Watts. It utilizes SMA connectors, specifically a male plug on one end and a female jack on the other, facilitating inline integration. The housing is constructed from stainless steel with a hexagonal nut design for secure installation using a torque wrench.

Feature Summary

• Stainless steel body construction for durability
• SMA male-to-female connector configuration
• Hexagonal nut design for torque wrench installation

Applications

• RF signal level adjustment in test and measurement equipment
• Signal conditioning in wireless communication systems
• Attenuation in microwave circuit designs

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as this model uses a male plug and female jack. Confirm that the operating temperature range of -55°C to +125°C aligns with the intended environmental conditions. Ensure the 2W power handling capacity is sufficient for the maximum expected signal power in the application to prevent component damage.

Selection Notes

Select this component when a 5 dB attenuation value is required within the DC to 18 GHz bandwidth. The choice is appropriate for applications demanding high power handling up to 2 Watts and robust mechanical stability provided by the stainless steel housing. Consider the SMA interface compatibility with existing cabling and fixtures before procurement.

Part Context

This part belongs to the L-com line of RF attenuators, which are passive components used to reduce signal strength without distortion. These devices are essential for protecting sensitive receivers and ensuring accurate signal levels in high-frequency environments. The series typically offers various attenuation values and connector types to suit diverse RF system architectures.

Replacement Considerations

LCAT1005-01 is listed as a parameter-equivalent substitute from the same manufacturer.
