LCAT1000-18

Overview

The LCAT1000-18 is a fixed RF attenuator manufactured by L-com, designed for signal level reduction in coaxial systems. It provides a nominal attenuation of 18 dB with a frequency range spanning from DC to 6 GHz. The component features SMA male-to-SMA female connectors and utilizes a hexagonal nut body constructed from passivated stainless steel for durability. It supports a maximum power handling capacity of 2 Watts and maintains a characteristic impedance of 50 Ohms, ensuring compatibility with standard RF infrastructure.

Feature Summary

• Fixed 18 dB attenuation value for precise signal control
• Broadband operation covering DC to 6 GHz frequency spectrum
• SMA male to SMA female interconnect configuration
• Passivated stainless steel housing with hexagonal nut design

Applications

• RF test and measurement setups requiring signal reduction
• Telecommunications equipment signal conditioning
• Wireless system component interfacing
• Laboratory circuit prototyping and validation

Procurement Notes

Verify the specific model suffix corresponds to the required 18 dB attenuation value, as the LCAT1000 series includes various attenuation levels. Confirm that the SMA male-to-female connector orientation matches the system cabling requirements. Ensure the operating environment temperature and power levels remain within the specified 2W limit and 6 GHz bandwidth to maintain performance integrity.

Selection Notes

Select this component when a fixed 18 dB loss is necessary between DC and 6 GHz frequencies. The SMA interface requires matching male and female ports in the signal chain. Consider the 2W power rating for high-power applications and the stainless steel construction for environmental resistance compared to other material options in the series.

Part Context

This part belongs to the LCAT1000 series of fixed attenuators from L-com. The series offers multiple attenuation values, such as 5 dB or 20 dB variants, sharing similar physical dimensions and connector types. The LCAT1000-18 specifically denotes the 18 dB attenuation option within this standardized line of coaxial components.

Replacement Considerations

Compatible substitutes include other LCAT1000 series models with identical connector interfaces if attenuation tolerance allows. Cross-manufacturer equivalents must match the 50 Ohm impedance, SMA gender configuration, and 6 GHz frequency range to ensure functional interchangeability without re-engineering.
