Abstract: Provided are apparatuses and methods for a tri-frequency feedchain configured to combine at least three frequency bands on a waveguide. The feedchain includes a turnstile configured to support two orthogonal fundamental modes and combine six filtered signals and a third signal and output the combined signal via an output port. The feedchain also includes at least six filters disposed about the turnstile configured to filter a split signal into the filtered signals. The turnstile is a junction for the filters and includes a port at the interface of each filter and the turnstile for receiving the filtered signal. The turnstile includes a third signal port configured to receive the third signal. The split signals are of an intermediary frequency band comprising a first and second frequency band and the third signal is of a third frequency band. The first, second, and third frequency bands do not intersect.

Abstract: This application describes an apparatus and system for a Wide band end launcher to convert a signal in a coaxial line to a CPW line. The apparatus uses a transition zone which gradually tapers in two inclined planes from the coaxial line to the CPW line, connecting the central conductor of the coaxial line to the central conductor of the CPW line. In addition, the outer conductor of the coaxial line is connected to the ground plates of the CPW line. This allows for high bandwidth transfers between the two types of lines for accurate measurements and other purposes.

Abstract: Aspects of the subject disclosure may include, for example, a coupling module that includes a waveguide that guides a first electromagnetic wave conveying data from a transmitting device. A dielectric coupler receives the first electromagnetic wave from the waveguide to form a second electromagnetic wave, and that guides the second electromagnetic wave along the dielectric coupler adjacent to a transmission medium, and wherein the dielectric coupler has a length that supports a cancellation of at least one cancelled wave mode from a coupling of the second electromagnetic wave to the transmission medium.

For example, a package structure includes a package substrate having an integrated waveguide, and first and second integrated circuit chips mounted to the package substrate. The first integrated circuit chip is coupled to the integrated waveguide using a first transmission line to waveguide transition, and the second integrated circuit chip is coupled to the integrated waveguide using a second transmission line to waveguide transition. The first and second integrated circuit chips are configured to communicate by transmitting signals using the integrated waveguide within the package carrier.
