ABSTRACT:
A signal transmission apparatus includes a first waveguide, a second waveguide and a third waveguide. The transitions between the first, second and third waveguides are substantially co-impedance matched. The signal transmission apparatus may be a multi-port device, and may be used to transition high frequency signals from one component to another in a variety of applications.
