摘要： The accuracy of an impedance tuner may be improved and the size may be reduced by using linear actuators instead of rotary motors. The linear actuator may be integrated with position sensors to allow very small size, and implemented with a servo system for best accuracy and speed. Spring loaded arms holding the mismatch probes allow the tuner to operate in any orientation to further fit into small spaces. The small size reduces losses by allowing direct connection to wafer probes for on-wafer measurement systems.

摘要： A coupler comprising a silicon substrate with one or more double slot radiators configured to transmit or receive an RF signal, a slot balun circuit configured to isolate the RF signal, and a grounded coplanar waveguide configured to propagate the RF signal in a horizontal direction. The coupler can be included on an integrated chip with a second coupler and the chip can be positioned over two waveguides such that each coupler is positioned within the center of each waveguide aperture.

摘要： A pseudo coaxial line is connected to a first coplanar line at a first connecting portion and connected to a second coplanar line at a second connecting portion. The first coplanar line and the second coplanar line are, for example, differential coplanar lines. Also, a back surface concave portion in which the second connecting portion of the pseudo coaxial line is exposed is provided. The back surface concave portion is formed into an almost semicircular shape, an almost semielliptical shape, or a rectangular shape in a planar view.

摘要： One embodiment provides an apparatus. The apparatus includes a first signal trace and a current return path. The current return path includes a plurality of portions. The plurality of portions includes a first portion, a second portion and a third portion. The first portion is included in a first power plane. The second portion is included in a second power plane coplanar with the first power plane and separated from the first power plane by a split. The third portion spans the split and is included in a reference voltage plane. The reference voltage plane is coplanar with the first signal trace. The reference voltage plane is separated from the first power plane and the second power plane by a dielectric material.

摘要： Embodiments of the invention include a packaged device with transmission lines that have an extended thickness, and methods of making such device. According to an embodiment, the packaged device may include a first dielectric layer and a first transmission line formed over the first dielectric layer. Embodiments may then include a second dielectric layer formed over the transmission line and the first dielectric layer. According to an embodiment, a first line via may be formed through the second dielectric layer and electrically coupled to the first transmission line. In some embodiments, the first line via extends substantially along the length of the first transmission line.

摘要： Embodiments of a circuit, system, and method are disclosed. In an embodiment, a circuit includes a first microstrip transmission line, a second microstrip transmission line, and a slotline formation, wherein the slotline formation extends between the first microstrip transmission line and the second microstrip transmission line so that the slotline formation is configured to electromagnetically couple the first microstrip transmission line to the second microstrip transmission line during operation of the circuit. In addition, the circuit includes at least one controllable capacitance circuit electrically connected to at least one of the first microstrip transmission line and the second microstrip transmission line, wherein a magnitude of capacitance of the at least one controllable capacitance circuit is controllable (e.g., in response to a capacitance control signal received at a control interface).

摘要： An adjustable frame assembly for augmented reality eyewear. The frame assembly includes a face portion for supporting at least one waveguide that creates an eye box, a support rest for supporting the face portion on a user, and a coupling for adjusting the position of the face portion relative to the support rest. This enables movement of the waveguide eye box relative to the support rest to position the eye box in front of the wearer's eyes.

摘要： Techniques for designing and fabricating quantum circuitry, including a coplanar waveguide (CPW), for quantum applications are presented. With regard to a CPW, a central conductor and two return conductor lines can be formed on a dielectric substrate, with one return conductor line on each side of the central conductor and separated from it by a space. The central conductor can have bridge portions that can be raised a desired distance above the substrate and base conductor portions situated between the bridge portions and in contact with the surface of the substrate; and/or portions of the substrate underneath the bridge portions of the central conductor can be removed such that the bridge portions, whether raised or unraised, can be the desired distance above the surface of the remaining substrate, and the base conductor portions can be in contact with other portions of the surface of the substrate that were not removed.

摘要： A transmission line includes a substrate, a high-frequency signal transmission line, a differential signal transmission line, and a power supply line. The substrate is insulating, extends in a predetermined direction, and internally includes each of the high-frequency signal transmission line, the differential signal transmission line, and the power supply line. The power supply line and the high-frequency signal transmission line are in parallel or substantially in parallel to each other, and the differential signal transmission line is between the power supply line and the high-frequency signal transmission line.
