LCAT1006-04

Overview

The LCAT1006-04 is a fixed RF coaxial attenuator manufactured by L-Com, designed for signal level reduction in high-frequency applications. It provides a nominal attenuation of 4 dB with a power rating of 2 Watts. The device operates across a frequency range from DC to 18 GHz and maintains a 50 Ohm impedance. It features SMA male-to-female connectors housed in a brass body with gold plating. Key electrical specifications include a maximum VSWR of 1.35:1 and an operating temperature range from -55°C to +125°C. The unit measures approximately 29.97 mm in length.

Feature Summary

• Provides stable 4 dB attenuation for precise signal control
• Operates effectively from DC up to 18 GHz
• Constructed with durable gold-plated brass housing

Applications

• Wireless communication systems for signal strength adjustment
• RF test and measurement setups requiring fixed attenuation
• Microwave circuit design for impedance matching and signal conditioning

Procurement Notes

Verify the specific attenuation value of 4 dB against system requirements before procurement. Confirm that the SMA male-to-female connector configuration aligns with existing cable assemblies. Ensure the 2W power handling capacity exceeds the maximum expected signal power in the application path. Check compatibility with the specified 18 GHz frequency limit to avoid performance degradation at higher frequencies.

Selection Notes

Select this component when a fixed 4 dB reduction is required within a 50 Ohm system. Consider the physical dimensions and weight if space constraints are critical. Evaluate the thermal environment to ensure operation remains within the -55°C to +125°C range. Compare VSWR specifications against other models if strict reflection limits are necessary for signal integrity.

Part Context

This part belongs to L-Com's passive RF attenuator series, specifically the LCAT1006 line. These components are engineered for interconnect applications where reliable signal attenuation is needed without active power sources. The series offers various attenuation values while maintaining consistent connector types and mechanical form factors for easy integration into standard RF infrastructure.

Replacement Considerations

Equivalent parts include Molex 0732870011 and Pasternack PE7487-1. Verify that substitute models match the 4 dB attenuation, 2W power rating, and 18 GHz frequency range. Ensure connector polarity (SMA Male-Female) and impedance (50 Ohms) remain identical to maintain system continuity.
