Abstract: A system includes at least one component configured to generate thermal energy, a heat spreader configured to remove thermal energy from the at least one component, and at least one substrate configured to remove thermal energy from the heat spreader. The heat spreader includes a first portion and a second portion. The first portion of the heat spreader is coupled to the substrate, and the second portion of the heat spreader is coupled to the at least one component. The first portion of the heat spreader includes high aspect-ratio structures that are separated from one another. The high aspect-ratio structures cause the first portion of the heat spreader to be pliable and able to accommodate a mismatch in coefficients of thermal expansion between a material in the heat spreader and a material in the substrate.

Abstract: A phase shifter is formed by providing a branchline coupler having a pair of phase adjusting sections. Each one of the phase adjusting sections is coupled to a corresponding one of a pair of shunt transmission line sections of the branchline coupler. Each one of the pair of phase adjusting sections includes: first and second conductive pads are disposed on the surface of a substrate having a gap between them; one of the pads being connected to a ground plane conductor on a bottom surface of the substrate. A series of conductive layer segment is sequentially written on the surface of the substrate in the gap electrically connected to sidewalls of the first and second pads. Phase shift through the phase shifter is measured after each one of the segments is written. The writing process is terminated when the measuring detects a predetermined phase shift through the phase shifter.

Abstract: A microwave transmission line structure having a pair of ground strip conductors on a surface of a dielectric substrate structure. A signal strip conductor is disposed on the surface of the dielectric substrate structure between the pair of ground strip conductors. A solid dielectric layer is disposed over: the signal strip conductor; the upper surface of the dielectric substrate structure between sides of each one of the ground strip conductors; and the signal strip conductor. An electrically conductive shield member is disposed on the solid dielectric layer and on, and in direct contact with, upper surfaces of the pair of ground strip conductors. The structure is used on each one of a plurality of proximate microwave transmission lines formed on the substrate structure to electrically isolate the transmission line.

Abstract: A method of tuning a circuit includes measuring an electrical characteristic of the circuit and forming, by an automated process, a conductive trace connected to the circuit to adjust the electrical characteristic of the circuit. The steps of measuring the electrical characteristic and forming the conductive trace are conducted simultaneously. The automated process involves adjusting a physical characteristic of the conductive trace in real-time in response to results of measuring the electrical characteristic of the circuit until the electrical characteristic of the circuit complies with a selected criterion.
