LCAT1005-30

Overview

The LCAT1005-30 is a fixed RF attenuator manufactured by L-com, designed for inline signal reduction within radio frequency circuits. It provides a nominal attenuation of 30 dB across a frequency range from DC to 18 GHz. The component features a 50 Ohm impedance and can handle a maximum power rating of 2 Watts. Mechanical construction includes an stainless steel body with a hexagonal nut design to facilitate installation using a torque wrench. The connector configuration consists of one SMA male plug and one SMA female jack, allowing for versatile integration into test setups and communication systems.

Feature Summary

• Stainless steel housing with hexagonal nut design for secure torque wrench installation
• SMA male to SMA female connector interface for flexible circuit integration
• Fixed 30 dB attenuation performance across DC to 18 GHz bandwidth

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• Protection of sensitive receiver inputs from high-power signals

Procurement Notes

Verify the specific datasheet provided by L-com or authorized distributors to confirm current manufacturing status and exact electrical tolerances. Ensure that the SMA male-to-female configuration matches the system requirements, as this model does not offer interchangeable connector options. Confirm thermal management capabilities align with the 2W power rating under expected operating conditions.

Selection Notes

Select this component when a precise 30 dB reduction is required up to 18 GHz. The stainless steel body offers durability suitable for rugged environments. The mixed SMA connector type simplifies cabling between standard male and female ports without requiring additional adapters. Consider the physical size constraints imposed by the hexagonal nut design during PCB or panel layout planning.

Part Context

This part belongs to L-com's line of RF fixed attenuators, which are passive components used to reduce signal amplitude without distortion. The LCAT series typically utilizes precision resistive elements housed in robust metal enclosures to maintain performance stability over temperature variations. These components are essential for maintaining signal integrity in high-frequency applications.

Replacement Considerations

Cross-reference with other L-com models offering identical 30 dB attenuation and SMA interfaces if availability is an issue. Verify that substitute parts match the 2W power handling and 18 GHz frequency limit. Ensure mechanical dimensions and mounting styles are compatible with existing assembly fixtures.
