LCAT1002-04

Overview

The LCAT1002-04 is a fixed RF attenuator from the L-com Passive series, designed for in-line coaxial applications. It provides a nominal attenuation of 4 dB with an accuracy of ±0.5 dB across a frequency range of DC to 3 GHz. The component features SMA male and female connectors and operates at a maximum power rating of 2 W within a 50 Ohm system. It exhibits a Voltage Standing Wave Ratio (VSWR) of less than 1.2:1. The unit functions reliably within an operating temperature range of -55°C to +125°C.

Feature Summary

• Coaxial in-line design with gold-plated brass body
• SMA male to SMA female connector configuration
• Wide operational temperature capability

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in 50 Ohm transmission lines
• Signal conditioning in wireless communication systems

Procurement Notes

Verify that the specific order matches the SMA male-to-female configuration and 4 dB attenuation value. Confirm compliance with RoHS3 standards and EAR99 classification requirements. Ensure the selected supplier can provide valid datasheets and technical drawings for integration validation. Check for any specific environmental testing documentation if extreme temperature operation is required.

Selection Notes

Select this model when a 4 dB attenuation is required between DC and 3 GHz frequencies. The 2 W power rating suits moderate signal levels. The SMA interface dictates compatibility with existing SMA-based infrastructure. Consider the physical dimensions and weight specifications for space-constrained installations compared to other attenuator types.
