Abstract
The present invention is a wideband directional coupler comprising first and second coupled transmission lines and first and second equalizers connected at opposite ends of the coupled portion of the second transmission line. Illustratively, the first and second equalizers are RC filters. The first and second equalizers are designed to have transmission characteristics that vary with frequency so as to offset the frequency variation of the coupling factor of the coupled transmission lines.
