LCAT1005-01

Overview

The LCAT1005-01 is a fixed RF attenuator from L-com, designed for frequencies ranging from DC to 18 GHz. It provides an attenuation value of 1 dB with an accuracy of ±0.5 dB. The device features SMA male to SMA female connectors and maintains a 50 Ohm impedance. It supports a maximum input power of 2 W and exhibits a Voltage Standing Wave Ratio (VSWR) of less than 1.30:1. The unit operates within a temperature range of -55°C to +125°C and is constructed with a stainless steel body.

Feature Summary

• Stainless steel construction for durability
• SMA male to female inline configuration
• Wide frequency operation up to 18 GHz

Applications

• RF signal path attenuation
• Test and measurement equipment
• Telecommunications systems

Procurement Notes

Verify the specific datasheet revision and connector gender configuration prior to ordering. Confirm that the operating environment temperature falls within the specified -55°C to +125°C range. Ensure the system impedance matches the 50 Ohm specification to maintain optimal VSWR performance. Check for any updated compliance documentation or environmental certifications required for your specific deployment region.

Selection Notes

Select this component when a low attenuation value of 1 dB is required at high frequencies up to 18 GHz. The SMA interface is suitable for standard coaxial connections. Consider the 2 W power rating for signal levels below this threshold. The stainless steel body offers robust mechanical protection compared to plastic alternatives.

Part Context

This part belongs to the L-com passive attenuator series, specifically the connectorized line. It is distinct from higher attenuation models like the LCAT1006-01 (1 dB SMA) or LCAT1007-09 (9 dB N-type). The product line focuses on reliable RF signal management across various connector types and attenuation values.

Replacement Considerations

Direct substitutes include other 1 dB SMA fixed attenuators from different manufacturers. Verify that replacement parts match the 18 GHz frequency limit, 50 Ohm impedance, and 2 W power handling capabilities. Connector gender and body material should also be confirmed for mechanical compatibility.
