LCAT1003-05

Overview

The LCAT1003-05 is a fixed RF attenuator manufactured by L-com. It provides a nominal attenuation of 5 dB with a maximum power handling capacity of 2 Watts continuous wave. The device operates within a frequency range of DC to 3 GHz and maintains a characteristic impedance of 50 Ohms. It utilizes N-type connectors, specifically configured as a plug-to-jack interface. The unit features a low voltage standing wave ratio (VSWR) of less than 1.2:1, ensuring efficient signal transmission in radio frequency applications.

Feature Summary

• Provides fixed 5 dB attenuation for signal level adjustment
• Supports high power handling up to 2 Watts continuous wave
• Operates across a broad frequency spectrum from DC to 3 GHz
• Features robust N-type connector interface for secure connections

Applications

• RF test systems
• Instrumentation
• Signal conditioning circuits

Procurement Notes

Verify the specific part number LCAT1003-05 against official L-com documentation to confirm the 5 dB attenuation value and 2W power rating. Ensure compatibility with N-type male-to-female interfaces. Check for RoHS compliance status and environmental specifications required for your deployment. Confirm that the DC to 3 GHz frequency range meets your system requirements before procurement.

Selection Notes

Select this component when a precise 5 dB reduction in RF signal strength is required within a 50 Ohm system. It is suitable for applications demanding high power tolerance up to 2 Watts and operation up to 3 GHz. Consider the N-type connector configuration for integration into existing test equipment or instrumentation setups requiring reliable, low-reflection connections.

Part Context

This model belongs to the LCAT1003 series of fixed attenuators from L-com. Similar variants in this series include models with different attenuation values such as 10 dB, 20 dB, and 30 dB, all sharing the same physical form factor, connector type, and general electrical characteristics like power handling and frequency range.

Replacement Considerations

Direct substitutes may include other LCAT1003 series parts with identical connector types but different attenuation values if adjustable levels are acceptable. Cross-brand replacements must match the 50 Ohm impedance, N-type interface, and 2W power rating while maintaining performance within the DC to 3 GHz range.
