Abstract
Disclosed are waveguide distortion mitigation devices that produce reduced group delay ripple in communication systems in which they are used. The devices comprise a first and second tapered waveguide sections, a first coupling device coupled to the first tapered waveguide section, and a second coupling device coupled to the second tapered waveguide section and the first waveguide coupling device. A waveguide isolator may optionally be coupled between the first and second waveguide coupling devices. The first and second coupling devices may comprise waveguide circulators or waveguide-hybrid couplers. The tapered waveguide sections may embody a single transition comprising a single waveguide wall, a single transition comprising two waveguide walls, or a plurality of transitions comprising a plurality of waveguide walls.
