LCAT1003-02

Overview

The L-com LCAT1003-02 is a fixed RF attenuator designed for in-line applications within the passive series. It provides a nominal attenuation of 2dB with an accuracy of ±0.4dB across a frequency range of 0 Hz to 3 GHz. The component features N-type male and female connectors, maintaining a 50 Ohm impedance. It supports a maximum input power of 2W and exhibits a VSWR of less than 1.20. The unit operates reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Provides precise 2dB signal reduction with high attenuation accuracy
• Supports DC to 3 GHz operational bandwidth
• Features robust brass construction for durability

Applications

• RF signal level adjustment in test and measurement setups
• Signal conditioning in wireless communication systems
• Component integration in microwave circuit designs

Procurement Notes

Verify that the replacement part matches the specific 2dB attenuation value and N-type connector configuration. Confirm the 50 Ohm impedance rating aligns with system requirements. Ensure the 2W power handling capacity meets the application's peak power demands. Check that the operating temperature range covers the intended environmental conditions. Validate the VSWR specifications against strict signal integrity needs.

Selection Notes

Select this model when a low attenuation value is required for precise signal management. The N-type interface offers reliable connectivity for frequencies up to 3 GHz. The 2W power rating suits moderate power levels common in laboratory environments. Consider the compact form factor for space-constrained installations. Verify compatibility with existing N-type cabling infrastructure.
