LCAT1005-09

Overview

The LCAT1005-09 is a fixed RF attenuator manufactured by L-com, providing a nominal attenuation of 9 dB. It operates within a frequency range of DC to 18 GHz and supports a maximum power handling capacity of 2 Watts. The device features a 50 Ohm impedance system and utilizes SMA connectors, specifically an SMA male plug on one end and an SMA female jack on the other. The housing is constructed from stainless steel with a hex nut design for secure installation.

Feature Summary

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

Applications

• RF signal path attenuation in high-frequency systems
• Test and measurement equipment setups
• Wireless communication infrastructure components

Procurement Notes

Verify the specific connector gender configuration (male-to-female) against system requirements before procurement. Confirm that the 2W power rating and 18 GHz frequency limit align with operational parameters. Ensure compatibility with standard SMA mating interfaces. Check for any specific mounting hardware requirements due to the hex nut design. Validate datasheet specifications for environmental operating conditions.

Selection Notes

Select this component when a 9 dB attenuation value is required within the 18 GHz bandwidth. The stainless steel body offers robustness suitable for demanding environments. The SMA interface ensures broad compatibility with existing coaxial systems. Consider the 2W power handling capability for signal levels exceeding lower-rated alternatives. The hex nut design aids in maintaining consistent connection integrity during assembly.

Part Context

This part belongs to L-com's line of fixed RF attenuators designed for coaxial applications. It shares the same connector type and general form factor as other models in the series but differs in attenuation value and potentially material composition. The model number suffix typically indicates the specific attenuation level, distinguishing it from variants like the LCAT1005-01 or LCAT1005-05.

Replacement Considerations

Direct substitutes must match the 9 dB attenuation, 18 GHz frequency range, 2W power rating, and SMA male-to-female configuration. Verify impedance matching at 50 Ohms. Ensure physical dimensions and mounting hole patterns are compatible if space constraints exist.
