Apparatus for signal transitioning from a device to a waveguide

摘要

A signal transmission apparatus (200) including a first waveguide (205), a second waveguide (207) and a third waveguide (215). 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.
