1. A device, comprising:
a printed circuit board component that comprises a bottom metal layer and a top metal layer, wherein the bottom metal layer is connected to the top metal layer by an array of metal posts, and wherein the array of metal posts is arranged to form a substrate integrated waveguide network configured to transmit a set of electromagnetic waves corresponding to a single-ended signal represented according to a bandwidth;
a coaxial to waveguide adaptor component comprising a coaxial cable port portion and a waveguide port portion, wherein the waveguide port portion guides the set of electromagnetic waves to the substrate integrated waveguide network;
a rectangular window component located on the bottom metal layer that affixes to the coaxial to waveguide adaptor component; and
a first coaxial terminal and a second coaxial terminal that couple a first subset and a second subset of electromagnetic waves of the set of electromagnetic waves thereby generating a transformed set of electromagnetic waves corresponding to an impedance bandwidth based on geometric parameters of the device.
