LCAT1000-15

Overview

The LCAT1000-15 is a fixed RF attenuator manufactured by L-com, designed for coaxial in-line applications. It features SMA male to SMA female connectors and operates within a frequency range of DC to 6 GHz. The component maintains a system impedance of 50 Ohms and supports a maximum continuous wave power handling capacity of 2 Watts. Key electrical specifications include an attenuation value of 15 dB with a tolerance of ±0.5 dB and a Voltage Standing Wave Ratio (VSWR) less than 1.3:1. The unit incorporates a hex nut on the body for secure mounting.

Feature Summary

• Coaxial in-line design with SMA male to SMA female connector interface
• Frequency operation from DC to 6 GHz with 50 Ohm impedance
• Hex nut construction on the body for mechanical stability

Applications

• Instrumentation systems
• Precision measurements
• Production test systems

Procurement Notes

Verify that the specific part number LCAT1000-15 matches the required 15 dB attenuation value and SMA connector configuration before procurement. Confirm that the 2 Watt power rating and 6 GHz frequency limit align with the operational requirements of the target circuit. Ensure the SMA male-to-female interface orientation is compatible with the existing cabling infrastructure to prevent connection mismatches.

Selection Notes

Select this component when a fixed 15 dB reduction is required for signals up to 6 GHz. The 2 Watt power handling capability makes it suitable for moderate power levels. The SMA interface is standard for many RF setups. Consider the physical size and hex nut mounting requirement if space or installation method is constrained. Verify that the VSWR specification meets the system's signal integrity needs.

Part Context

The LCAT1000 series represents a line of fixed RF attenuators from L-com. The LCAT1000-15 specifically denotes the variant with 15 dB attenuation. This series utilizes a robust coaxial design intended for reliable performance in various RF environments. The model number suffix typically indicates the attenuation value, distinguishing it from other variants in the same product family.

Replacement Considerations

Direct substitutes must match the 15 dB attenuation, SMA male-to-female interface, DC-6 GHz frequency range, and 50 Ohm impedance. Check for equivalent power ratings of at least 2 Watts. Verify that any replacement component offers comparable VSWR performance below 1.3:1 to maintain signal quality.
