    Abstract: A method, an apparatus, and a system product for mixing radio frequency signals are provided. In one aspect, the apparatus is configured to perform switching of switches based on first, second, third, and fourth phased half duty clock signals. The apparatus convolves a differential input signal on a differential input port with the first, second, third, and fourth phased half duty cycle clock signals to concurrently generate a differential in-phase output signal and a differential quadrature-phase output signal on a dual differential output port. The first, second, third, and fourth phased half duty cycle clock signals are of the same frequency and out of phase by a multiple of ninety degrees with respect to each other.

    Abstract: A device that includes a first board, a second board, and coaxial cable coupled to the first board and the second board. The coaxial cable includes a multi-line coaxial cable configured to provide at least two electrical paths for electrical currents between the first board and the second board. A first plug is coupled to the first board. A second plug is coupled to the second board. The coaxial cable includes a first receptable and a second receptable. The first receptable is configured to couple to the first plug. The second receptable is configured to couple to the second plug. The coaxial cable is configured to provide (i) a first electrical path for a first electrical current between the first board and the second board, and (ii) a second electrical path for a second electrical current between the first board and the second board.

    Abstract: Apparatus, methods, and computer-readable media for implementing a display-side antenna are disclosed herein. An example apparatus for wireless communication includes a housing and a display device supported by the housing. The example display device includes at least a glass cover and a panel positioned between the glass cover and an internal surface of the housing. The panel may be configured to output graphical content for presentment on the glass cover via pixels arranged within a visible area of the panel. The example apparatus also includes an antenna array. The antenna array may be configured to facilitate wireless communication at the apparatus. The antenna array may be positioned to overlap a portion of the visible area of the panel and configured to allow graphical content output by the panel to display on the glass cover at the overlapped portion of the visible area.
