International Classification:

H01B 11/20
H01B 11/18

Abstract:

A coaxial transmission line structure having a center conductor section having an input contact and an output contact the output contact being larger than the input contact, the center conductor having a plurality of different geometrically shaped, electrically conductive layers having sizes progressively increasing from the input contact to the larger output contact to conductor transition from the input contact to the larger output contact, the electrically conductive layers being electrically interconnected by staggered microvias passing through dielectric layers to the center, and (B) an outer conductor section disposed about, coaxial with, and electrically isolated from, the center conductor by the dielectric layers.

International Classification:

H01Q 3/34
G01S 13/02

Abstract:

A via-less beamformer provided from a plurality of circuits elements having circuit layouts selected to mitigate unwanted reactive coupling there between. At least one of the plurality of circuit elements is provided having a circuit layout selected based upon reactive field theory. In one embodiment, a circuit layout may be selected by: determining which circuit features of the circuit elements produce reactive fields in response to a signal provided thereto, separating the total field into a modal set and determining the modal weighting coefficients based on geometrical and/or design features of the of the circuit elements. In one embodiment the via-less beamformer comprises one or more via-less combiner/divider circuits. In one embodiment the via-less beamformer comprises one or more branch hybrid coupler circuits. In one embodiment the via-less beamformer comprises one or more via-less combiner/divider circuits and one or more branch hybrid coupler circuits.

International Classification:

H03F 3/60
H03F 3/21

Abstract:

A power amplifier structure having: a power divider for dividing power in a signal fed to an input port between a pair of output ports. Each one of a pair of amplifiers has: an input coupled to a corresponding one of the pair of power divider output ports; and an output. A power combiner is provided. Signals at the power divider output ports are fed to the inputs of the pair of amplifiers in a forward direction and then pass through the amplifiers in the forward direction towards the outputs of the pair of amplifiers. Connectors direct the signals at the amplifier outputs to the power combiners, the signal then passing through the power combiner to an output port in a direction opposite to the forward direction.
