LCAT1006-20

Overview

The LCAT1006-20 is a fixed RF attenuator from the L-com Passive series, designed for in-line signal reduction. It provides a nominal attenuation of 20 dB across a frequency range of DC to 18 GHz. The component features SMA male-to-female connectors and operates with a 50 Ohm impedance. It supports a maximum power rating of 2 Watts and maintains a VSWR of 1.35:1. The unit measures 29.97 mm in length and weighs 10 grams. It functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides precise 20 dB signal attenuation for RF applications
• Operates effectively from DC up to 18 GHz frequency range
• Features durable gold-plated brass construction with SMA connectors

Applications

• RF test and measurement setups requiring signal reduction
• Wireless communication systems operating at high frequencies
• Signal conditioning in microwave circuitry

Procurement Notes

Verify part authenticity through authorized L-com distributors or certified suppliers. Confirm that the received component matches the LCAT1006-20 designation and includes original packaging documentation. Check connector integrity and surface finish against datasheet specifications. Ensure storage conditions prevent corrosion prior to installation. Request batch-specific calibration data if required for precision applications.

Selection Notes

Select this model when a fixed 20 dB loss is required within an 18 GHz bandwidth. Choose based on the need for SMA interface compatibility and 2W power handling capacity. Consider the physical dimensions and weight constraints for integration into existing RF assemblies. Evaluate thermal performance requirements against the specified operating temperature range.

Part Context

This component belongs to the L-com Passive series of connectorized attenuators. It is part of a family offering various attenuation values, such as 1dB, 6dB, and 30dB options, all sharing similar SMA connectivity and frequency capabilities. The series is designed for reliable performance in general RF environments.

Replacement Considerations

Compatible substitutes include other L-com models like LCAT1006-01, LCAT1006-06, or LCAT1006-30 for different attenuation levels. Cross-brand replacements must match the 20 dB value, 18 GHz limit, and SMA plug-jack configuration.
