RF directional couplers

Directional couplers for RF and microwave applications

RF directional couplers are passive components used for controlled signal sampling in radio frequency and microwave systems. They are commonly applied in measurement, monitoring and test scenarios where signal analysis is required without interfering with the main transmission line.

Selection criteria

Choosing the right directional coupler depends on several technical factors related to the RF system architecture and the specific application. Key aspects to consider include:

• operating frequency range
• required coupling level
• directivity and port isolation
• power handling capability
• connection type and system integration

Available configurations

The catalog includes RF directional couplers designed for different application scenarios, suitable for telecommunications systems, test equipment and industrial instrumentation. Available solutions address a wide range of signal measurement and monitoring requirements in RF and microwave environments.
