LCAT1006-30

Overview

The LCAT1006-30 is a fixed RF attenuator from the L-Com Passive series, designed for in-line applications. It provides a nominal attenuation of 30 dB with an accuracy of ±0.5 dB across a frequency range of DC to 18 GHz. The component features SMA male and female connectors and operates at a maximum power rating of 2 W. It maintains a VSWR of less than 1.35:1 and has a characteristic impedance of 50 Ohms. The unit measures 29.97 mm in length and weighs 10 g, functioning within a temperature range of -55°C to +125°C.

Feature Summary

• Coaxial in-line design with gold-plated brass body
• SMA male to SMA female connector configuration
• Wideband operation from DC to 18 GHz

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in microwave communication systems
• Protection of sensitive receiver inputs from high power signals

Procurement Notes

Verify the specific datasheet version for the LCAT1006-30 to confirm current manufacturing status and compliance certifications. Ensure that the SMA connector gender and mating requirements align with the system interface. Check for any supply chain restrictions or limited availability notices associated with this part number before finalizing procurement plans.

Selection Notes

Select the LCAT1006-30 when a precise 30 dB attenuation value is required within the DC to 18 GHz bandwidth. This model is suitable for systems utilizing 50 Ohm impedance and SMA interfaces. Consider the 2 W power handling capability and the operating temperature range of -55°C to +125°C to ensure compatibility with the environmental conditions of the intended application.

Part Context

This component belongs to the L-Com LCAT1006 series of passive RF attenuators. The series offers various attenuation values while maintaining consistent physical dimensions and connector types. The LCAT1006-30 specifically addresses applications requiring significant signal reduction, complementing lower attenuation models like the LCAT1006-01 (1 dB) within the same product family.

Replacement Considerations

Direct substitutes include other L-Com LCAT1006 series attenuators with identical SMA interfaces and frequency ranges but different attenuation values, such as the LCAT1006-06 or LCAT1006-10. Cross-brand replacements must match the 50 Ohm impedance, SMA gender, 2 W power rating, and 18 GHz maximum frequency specifications.
