LCAT1005-06

Overview

The LCAT1005-06 is a fixed RF attenuator manufactured by L-com, designed for high-frequency signal management. It provides a nominal attenuation of 6 dB with an accuracy of ±0.5 dB across a frequency range from DC to 18 GHz. The component supports a maximum input power of 2 Watts and maintains a characteristic impedance of 50 Ohms. It features SMA connectors in an in-line module configuration. The unit operates within a temperature range of -55°C to 125°C and exhibits a voltage standing wave ratio (VSWR) of less than 1.30:1.

Feature Summary

• Provides precise 6 dB signal attenuation for RF applications
• Operates effectively from DC up to 18 GHz frequency range
• Supports 2W maximum input power handling capacity
• Constructed with durable stainless steel housing

Applications

• RF signal level reduction in test and measurement equipment
• Impedance matching in microwave communication systems
• Protection of sensitive receiver inputs from high power signals
• Signal conditioning in wireless infrastructure components

Procurement Notes

Verify the specific connector gender configuration, as SMA male-to-female variants exist within this series. Confirm that the 6 dB attenuation value aligns with system requirements rather than assuming generic availability. Ensure environmental specifications meet operational temperature needs. Cross-reference the manufacturer part number LCAT1005-06 directly with official L-com documentation to avoid confusion with similar models like LCAT1005-30.

Selection Notes

Select this component when a fixed 6 dB attenuation is required at frequencies up to 18 GHz. The 2W power rating suits moderate power levels but may be insufficient for high-power transmission lines. Consider the SMA interface compatibility with existing cabling. The wide operating temperature range allows use in demanding environments. Stainless steel construction offers durability compared to plated alternatives.

Part Context

This model belongs to L-com's line of coaxial in-line RF attenuators. It shares the same physical form factor and frequency capabilities as other variants in the series, such as the 30 dB version. The primary distinction lies in the specific attenuation value provided. These components are typically used as passive interconnect devices in RF circuits requiring precise signal control without active power sources.

Replacement Considerations

Direct substitutes include other manufacturers' 6 dB SMA attenuators rated for DC-18 GHz and 2W. Verify mechanical dimensions and connector thread standards match existing assemblies. Ensure equivalent VSWR and power handling capabilities. Generic replacements must maintain 50 Ohm impedance to prevent signal reflection issues in high-frequency applications.
