LCAT1006-09

Overview

The LCAT1006-09 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in coaxial systems. It provides a nominal attenuation of 9 dB with an accuracy of ±0.5 dB. The device operates within a frequency range from DC to 18 GHz and supports a maximum input power of 2 Watts. It features SMA male-to-SMA female connectors and maintains a Voltage Standing Wave Ratio (VSWR) of less than 1.35:1. The unit is constructed from brass with gold plating and functions within an operating temperature range of -55°C to 125°C.

Feature Summary

• Provides precise 9 dB signal attenuation for RF applications
• Operates across a wide bandwidth from DC to 18 GHz
• Supports high power handling up to 2 Watts
• Features durable gold-plated brass construction

Applications

• RF signal level adjustment in wireless communication systems
• Test and measurement equipment calibration
• Protecting sensitive receiver components from high-power signals

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as this model utilizes SMA male to SMA female interfaces. Confirm that the operational environment stays within the specified -55°C to 125°C temperature range. Ensure the applied RF signal does not exceed the 2 Watt maximum power rating to prevent component damage. Check for any required certifications or compliance standards relevant to the intended deployment region before finalizing procurement.

Selection Notes

Select this component when a fixed 9 dB reduction is required at frequencies up to 18 GHz. Consider the 2 Watt power rating for high-power transmission lines. The SMA interface compatibility should be verified against existing cabling infrastructure. Evaluate the VSWR specification to ensure impedance matching requirements are met for minimal signal reflection in the target application circuit.

Part Context

This part belongs to L-com's series of coaxial fixed attenuators designed for RF and wireless applications. These components are engineered to provide stable attenuation values across broad frequency bands. The series typically includes various attenuation levels and power ratings to suit different system needs. The LCAT1006-09 specifically addresses scenarios requiring moderate signal reduction with high-frequency performance capabilities.

Replacement Considerations

Direct substitutes include other 9 dB fixed attenuators from L-com with compatible SMA interfaces and similar power ratings, such as variants within the same LCAT series. Verify that any replacement maintains the DC-18 GHz frequency range and 2 Watt power handling capacity. Ensure connector genders match the existing assembly to avoid adapter usage.
