LCAT1000-05

Overview

The LCAT1000-05 is an RF fixed attenuator manufactured by L-com, designed for in-line signal reduction applications. It provides a nominal attenuation of 5 dB across a frequency range from DC to 6 GHz. The component features SMA connectors, specifically a male plug on one end and a female jack on the other, facilitating coaxial integration. It supports an input power rating of 2 W and operates with a characteristic impedance of 50 Ohms. The housing is constructed from stainless steel, offering durability and shielding. This module is suitable for environments requiring stable attenuation performance within the specified bandwidth.

Feature Summary

• Coaxial in-line design with hex nut body for secure mounting
• SMA male to SMA female connector configuration
• Stainless steel construction for environmental robustness

Applications

• RF signal path attenuation in test and measurement equipment
• Signal level adjustment in wireless communication systems
• Protection of sensitive receiver inputs in radar systems

Procurement Notes

Verify that the specific part number LCAT1000-05 matches the required 5 dB attenuation value and SMA gender configuration (Plug to Jack). Confirm that the 2 W power handling and 50 Ohm impedance align with system requirements. Ensure the operating temperature range of -65°C to +125°C is compatible with the intended environment. Cross-reference datasheets to confirm material specifications and connector compatibility before purchase.

Selection Notes

Select this component when a fixed 5 dB attenuation is required between DC and 6 GHz. The SMA interface dictates compatibility with existing SMA-based cabling and fixtures. Consider the 2 W power limit for high-power applications. The stainless steel body offers advantages in harsh environments compared to plated variants. Ensure the physical size and hex nut mounting style fit within the available space constraints of the assembly.

Part Context

The LCAT1000 series comprises RF fixed attenuators from L-com, characterized by their coaxial in-line design and hex nut bodies. These components are engineered for reliable signal attenuation in radio frequency circuits. The series typically includes various attenuation values and connector configurations, serving as essential passive components for managing signal levels in RF systems. The LCAT1000-05 represents a specific variant within this family, defined by its 5 dB attenuation and SMA interface.

Replacement Considerations

Direct substitutes must match the 5 dB attenuation, DC-6 GHz frequency range, 50 Ohm impedance, and 2 W power rating. Connector compatibility requires SMA male-to-female interfaces. Verify that alternative parts offer similar VSWR performance and temperature stability. Generic RF attenuators may differ in connector quality or power handling capabilities.
