LCAT1005-04

Overview

The LCAT1005-04 is a fixed RF attenuator manufactured by L-com, designed for in-line coaxial applications. It provides an attenuation value of 4 dB with a power handling capacity of 2 W. The device operates within a frequency range from DC to 18 GHz and maintains a characteristic impedance of 50 Ohms. The physical interface consists of SMA male connectors on both ends, facilitating direct connection between compatible components. Constructed with a stainless steel body, the unit ensures durability and consistent performance across specified operational conditions.

Feature Summary

• Provides precise 4 dB signal attenuation for RF circuitry
• Supports high power handling up to 2 Watts
• Operates effectively across a broad DC to 18 GHz bandwidth
• Features durable stainless steel construction for environmental resilience

Applications

• RF signal level adjustment in test and measurement equipment
• Attenuation insertion in wireless communication systems
• Signal conditioning in microwave instrumentation setups

Procurement Notes

Verify the specific part number LCAT1005-04 against official L-com documentation to confirm the 4 dB attenuation value and SMA plug-to-jack configuration. Ensure compatibility with 50 Ohm system impedance requirements. Check manufacturer specifications for operating temperature ranges and power ratings prior to integration into final designs.

Selection Notes

Select this component when a fixed 4 dB reduction is required in high-frequency applications up to 18 GHz. The 2 W power rating suits moderate signal levels. The SMA interface mandates matching connector types on adjacent components. Stainless steel housing offers robustness compared to lighter materials, suitable for industrial or field-deployable environments requiring stable electrical characteristics.

Part Context

This model belongs to the LCAT1005 series of fixed attenuators from L-com. Variants within this series differ primarily in their attenuation values, such as 3 dB or 9 dB options, while sharing similar form factors and interface standards. The series supports general RF infrastructure needs where predictable signal loss is necessary for system calibration or protection.

Replacement Considerations

Compatible substitutes include other L-com models like LCAT1006-04, which shares identical electrical specifications but may differ in connector gender configuration. Cross-reference datasheets to ensure exact match in attenuation, frequency range, and power handling before substitution.
