LCAT1005-20

Overview

The LCAT1005-20 is a fixed RF attenuator from L-com designed for coaxial in-line applications. It provides a nominal attenuation of 20 dB with an accuracy of ±0.5 dB across a frequency range of DC to 18 GHz. The component features a 50 Ohm impedance and supports a maximum input power of 2 Watts. Constructed with stainless steel housing, it operates within a temperature range of -55°C to 125°C. The unit utilizes SMA connectors, specifically male to female configuration, and maintains a VSWR of less than 1.30:1.

Feature Summary

• Coaxial in-line design with hex nut body for secure installation
• Stainless steel construction for durability and shielding
• SMA male to female connector interface

Applications

• RF signal level reduction in test and measurement setups
• Protection of sensitive receiver inputs in communication systems
• Integration into microwave circuit boards and modules

Procurement Notes

Verify the specific datasheet version provided by L-com or authorized distributors to confirm current manufacturing specifications. Ensure that the SMA connector gender matches the system requirements, as this model specifies male-to-female configuration. Cross-reference the part number with official L-com catalogs to avoid confusion with similar series components having different attenuation values or power ratings.

Selection Notes

Select this component when a precise 20 dB attenuation is required up to 18 GHz. Consider the 2W power handling capability against expected signal levels. The stainless steel body offers robustness suitable for harsh environments. Verify that the SMA interface aligns with existing cabling and equipment ports before procurement.

Part Context

This model belongs to the LCAT1005 series of fixed attenuators from L-com. The series includes variants with different attenuation values such as 1dB, 3dB, and 30dB, all sharing similar form factors and performance characteristics like the 50 Ohm impedance and SMA connectivity. This specific part is optimized for high-frequency applications requiring stable attenuation.

Replacement Considerations

Direct substitutes include other LCAT1005 series parts if attenuation needs change, such as LCAT1005-01 or LCAT1005-03. Third-party equivalents must match the 20 dB value, 18 GHz frequency limit, and SMA male-female interface. Ensure replacement units meet the same 2W power rating and temperature specifications.
