Abstract :
Single-section and two-section nonsymmetrical directional couplers are introduced, providing large impedance transformation ratios, total matching, perfect directivity, almost unity coupling and flat delay across a 100% relative bandwidth. Design parameters are given and alternative physical implementations are discussed.
