SMW42HC001-20

RF Directional Couplers Overview

The SMW42HC001-20 is a general-purpose RF directional coupler manufactured by Fairview Microwave. It operates within a frequency range of 18 GHz to 26.5 GHz and provides a nominal coupling factor of 20 dB with a tolerance of ± 0.8 dB. The component utilizes WR-42 waveguide technology, featuring a broadwall configuration for signal coupling. It incorporates UG-595/U square cover flanges for mechanical interface stability and includes an E-plane coupled port for precise signal extraction. This module is designed for high-frequency applications requiring reliable signal monitoring and power measurement in microwave systems.

RF Directional Couplers Feature Summary

• Features a broadwall design with an E-plane coupled port for signal directionality
• Incorporates UG-595/U square cover flanges to ensure secure mechanical mounting

RF Directional Couplers Applications

• RF signal monitoring in microwave communication systems
• Power measurement and analysis in radar equipment
• Test and measurement setups requiring directional signal sampling

RF Directional Couplers Procurement Notes

Verify that the required waveguide interface matches the UG-595/U square cover flange specification. Confirm that the operating environment supports the WR-42 waveguide dimensions and the specified 18 GHz to 26.5 GHz frequency range. Ensure system requirements align with the 20 dB coupling tolerance of ± 0.8 dB for accurate signal processing.

RF Directional Couplers Selection Notes

Select this component when a waveguide-based directional coupler is necessary for frequencies above 18 GHz. The choice depends on the need for an E-plane coupled port and compatibility with standard WR-42 waveguide systems. Consider the physical constraints imposed by the square cover flanges and the specific coupling accuracy required for the application.
