摘要： A pulse of terahertz radiation is transmitted through a touch panel formed of a dielectric material. The pulse generates an employable evanescent field in a region adjacent to a touch surface of the touch panel. The terahertz radiation has a frequency range between 0.1 terahertz and 10 terahertz. A reflected pulse is generated from an object located within the region adjacent to the touch surface of the touch panel. A position is triangulated of the object on the touch surface of the touch panel, based at least in part on the reflected pulse.

摘要： An apparatus is provided. Transmission line cells are formed in a first region. A first metallization layer is formed over the transmission line cells within a portion of the first region. At least a portion of the first metallization layer is electrically coupled to the plurality of transmission line cells. A second metallization layer is formed over the first metallization layer with an interconnect portion, and overlay portion, and a first balun. The interconnect portion at least partially extends into the first region, and the overlay portion is within the first region. The first balun winding is electrically coupled to the overlay portion and partially extends into a second region. The first region partially surrounds the second region. A third metallization layer is formed over the second metallization layer having a second balun winding within the second region, where the second winding is generally coaxial with the first balun winding.

摘要： A radio frequency (RF) loopback substrate or printed circuit board (PCB) which contains receive and transmit antennas located on the bottom of the loopback substrate which are aligned with the complementary transmit and receive antennas on an antenna on package (AOP) device under test. The loopback substrate receive and transmit antennas are coupled to each other. The device under test contacts are driven by a conventional tester, which causes RF circuitry in the integrated circuit to drive an AOP transmit antenna. The corresponding loopback substrate receive antenna receives the RF signal from the AOP transmit antenna and provides it to the loopback substrate transmit antennas. The integrated circuit package AOP receive antennas then receive the RF signals from the loopback substrate transmit antennas. The signals at the integrated circuit package AOP receive antennas are monitored through the integrated circuit contacts to monitor the received RF signals.

摘要： A device comprises a package substrate and a ball grid array (BGA). The package substrate encapsulates an integrated circuit (IC) die and comprises a signal launch configured to emit or receive a signal on a surface of the package substrate. The BGA is affixed to the surface and comprises a set of grounded solder balls arranged as a boundary around the signal launch. The device may further comprise a printed circuit board (PCB) substrate having a waveguide interface side opposite a secondary waveguide side and a through-hole cavity that extends from the waveguide interface side to the secondary waveguide side, perpendicular to a plane of the PCB substrate. The BGA couples the package substrate to the waveguide interface side such that the surface of the package substrate faces the through-hole cavity and the signal launch and through-hole cavity are substantially aligned.
