Abstract
A microwave directional coupler includes a microstrip conductor formed on a dielectric substrate and forming a main transmission line having in and out ports that receive signals to be coupled. A substantially U-shaped microstrip conductor is formed over the dielectric substrate adjacent to the main transmission line and forms a secondary transmission line having a coupling section and coupler port. A load resistor is formed within the secondary transmission line, and the coupling section is less than a quarter wavelength of a center frequency.
