LCAT1003-04

Overview

The LCAT1003-04 is a fixed RF attenuator manufactured by L-com, designed for precise signal level reduction in radio frequency circuits. It provides a nominal attenuation value of 4 dB across a frequency range extending from DC to 3 GHz. The component supports a maximum continuous wave power handling capacity of 2 Watts and utilizes N-type connectors for interface compatibility. With a typical voltage standing wave ratio (VSWR) less than 1.2:1, it ensures high signal integrity and low reflection within its operational bandwidth.

Feature Summary

• N-Type connector interface for standard RF system integration
• Operates effectively from DC up to 3 GHz frequency range
• Handles maximum continuous wave power of 2 Watts
• Maintains VSWR below 1.2:1 for minimal signal reflection

Applications

• RF instrumentation systems
• Radio frequency test and measurement setups
• Signal conditioning in communication links

Procurement Notes

Verify the specific datasheet version when ordering to ensure compliance with current manufacturing standards. Confirm that the N-type connector gender configuration matches the system requirements, as variations may exist within the product family. Cross-reference the part number with official L-com documentation to validate the 4 dB attenuation specification and 2W power rating before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 4 dB reduction is required within a 50 Ohm system operating up to 3 GHz. Ensure the application does not exceed the 2 Watt CW power limit to prevent damage. Consider the physical size and connector type compatibility with existing N-type ports. This model is suitable for applications demanding stable attenuation without variable adjustment capabilities.

Part Context

The LCAT1003-04 belongs to L-com's series of fixed RF attenuators, which are engineered for consistent performance in microwave and RF environments. These components typically feature robust internal resistor networks to maintain accuracy over temperature variations. The series supports various attenuation values and connector types, providing modular solutions for signal management in complex electronic architectures.

Replacement Considerations

Direct substitutes include other LCAT1003 series variants with different attenuation values, such as LCAT1003-10 or LCAT1003-30, if the dB value differs. Generic replacements must match the N-type interface, 50 Ohm impedance, 2W power rating, and DC-3 GHz frequency range to ensure functional equivalence.
