LCAT1000-04

Overview

The LCAT1000-04 is a fixed RF attenuator manufactured by L-com, designed for coaxial in-line applications. It features SMA male to SMA female connectors and provides a nominal attenuation of 4 dB. The component operates within a frequency range of 0 Hz to 6 GHz and maintains a characteristic impedance of 50 Ohms. It supports a maximum power handling capacity of 2 Watts. The housing includes a hex nut on the body for secure installation.

Feature Summary

• Coaxial in-line design with SMA male to SMA female interface
• Fixed 4 dB attenuation value
• Operates from DC to 6 GHz frequency range
• Hex nut body construction for mechanical stability

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in 50 Ohm transmission lines
• Protection of sensitive receiver inputs from high power signals

Procurement Notes

Verify the specific model suffix corresponds to the required attenuation value. Confirm connector gender compatibility with existing cable assemblies. Ensure operating power levels remain within the 2W limit. Check frequency specifications against application requirements up to 6 GHz.

Selection Notes

Select this component when a precise 4 dB reduction is needed in a 50 Ohm system. Consider the SMA interface type for connection compatibility. Evaluate the 6 GHz bandwidth requirement against the application's highest frequency signal. Assess thermal management needs relative to the 2W power rating.

Part Context

This part belongs to the LCAT1000 series of fixed attenuators from L-com. The series offers various attenuation values while maintaining consistent physical dimensions and connector types. The LCAT1000-04 specifically denotes the 4 dB variant within this product line.

Replacement Considerations

Compatible substitutes include other 4 dB SMA fixed attenuators from manufacturers such as Pasternack or Mini-Circuits. Verify that replacement parts match the 50 Ohm impedance and 6 GHz frequency range. Ensure physical dimensions and mounting style are compatible with the existing assembly.
