An electronic assembly including a thermal capacitor. An electronic substrate of the electronic assembly includes one or more insulating layers and one or more conductor layers provided along the one or more insulating layers. The one or more conductor layers including a conductive material. A shape memory thermal capacitor is received in the electronic substrate. The shape memory thermal capacitor includes a shape memory core including a shape memory material.

Shape memory thermal capacitor and methods for same

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.

Coaxial transmission line structure

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.
