    Abstract: A high-speed transmission circuit comprises, as part of a signal path, a connector pin disposed on a pad that comprises an unused pad region. The unused pad region is not considered part of the signal path but is part of a resonant sub-circuit. In various embodiments, by properly adjusting the dimensions of the pad region and other structures in the high-speed transmission circuit, resonant frequencies of the sub-circuit are shifted to a frequency range that is outside of the frequency range of interest in the signal path, thereby, reducing insertion loss and increasing signal integrity without compromising mechanical stability.

    Abstract: An electronic device includes a first circuit operating on a first signal of a first frequency and a second circuit operating on a second signal of a second frequency. The first signal is different from the second signal, and the first circuit and the second circuit share a first component. The first component functions as an antenna for the second circuit, which reduces space occupied by a dedicated or independent antenna and achieves smaller size and better industrial design for the electronic device.

    Abstract: A phased array antenna system includes a flexible printed circuit board formed of a flexible material. The flexible printed circuit board includes a component layer, an antenna layer, and a phase matching layer between the component layer and the antenna layer. A control unit is coupled to the component layer. A plurality of antenna elements are coupled to the antenna layer. A plurality of signal paths extend through the component layer, the phase matching layer, and the antenna layer. Each of the plurality of signal paths connects the control unit to a respective one of the plurality of antenna elements. The control unit provides an independent phase controllable source, which allows beams emitted from the antenna elements to be steered.

    Abstract: A circuit board includes an insulating substrate including a wiring conductor and a first resin substrate that is made of a resin different from the insulating substrate and is laminated on the insulating substrate. The first resin substrate has a plurality of internal conductors located from a surface thereof facing the insulating substrate to a surface on a side opposite to the insulating substrate. Each of the plurality of internal conductors includes a part that is inclined with respect to a perpendicular to the surface facing the insulating substrate. Intervals at which the plurality of internal conductors are located on the side opposite to the insulating substrate are narrower than intervals at which the plurality of internal conductors are located on an insulating substrate side.

    Abstract: A transmission line includes connecting portion connected to the outside and a main body connected to the connecting portion. The connecting portion includes a terminal electrode connected to an external electrode, a signal conductor, and a ground conductor. The main body includes the signal conductor and the ground conductor. The connecting portion includes a first region including the terminal electrode, a second region adjacent to the first region along a signal transmission path, and a third region located between the second region and the main body. Impedance matching at the at least one of the connecting portions is achieved by the first region, the second region, and the third region.

    Abstract: A printed circuit board (PCB) for high-speed transmission is provided. The PCB includes: a plurality of circuit layers having one or more differential signal wires; a ground via, an anti-pad, and a signal via pair. The one or more differential signal wires have a first differential signal wire width on the plurality of circuit layers. The ground via provides a ground terminal to the plurality of circuit layers. The signal via pair is for connecting the plurality of circuit layers via a through-hole, so that the one or more differential signal wires pass through the anti-pad and pin through the plurality of circuit layers for signal transmission via the signal via pair. The one or more differential signal wires have a second differential signal wire width on the anti-pad, wherein the second differential signal wire width is greater than the first differential signal wire width.
