Abstract
A 20 to 500 MHz directional coupler for use in a high power RF system uses a pair of transmission line sections electrically interconnected in series by their shield terminals. The primary signal is passed through one of the line sections, and the second section is connected to ground through a resistor. The forward voltage is thus the voltage between the shield of the first line section and ground across the second line section.
