Outline Drawing
Note
Directional coupler allows the user to sample power on a transmission line with a given coupling factor. Crucially, a directional coupler will (ideally) sample power in just one direction, discriminating between forward and backward travel signals. The selectivity with which the coupler can select between front and reverse waves is called directionality, and is usually the most important factor in selecting a directional coupler. Other important factors include return loss, coupling value, coupling leveling, insertion loss, and power handling. For detailed information on all couplers, refer to the Microwave Power Splitters and Couplers Primer and the Application Note for Directivity and VSWR Measurements.
