    Abstract: A system is provided in which a set of modules each have a substrate on which is mounted a radio frequency (RF) transmitter and/or an RF receiver coupled to a near field communication (NFC) coupler located on the substrate. Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a field confiner located between the NFC coupler and the port region on the housing configured to guide electromagnetic energy emanated from the NFC coupler through the port region to a port region of an adjacent module.

    Abstract: A quadrature voltage controlled oscillator (QVCO) for providing an oscillating output signal. The QVCO includes a first oscillating circuit for producing a first output signal and a second output signal, those signals being a first set of antiphase signals. The QVCO also includes a second oscillating circuit for producing a first output signal and a second output signal, those signals being a second set of antiphase signals. The first oscillating circuit also has injection circuitry for injecting the second set of antiphase signals without a DC bias into the first output signal and the second output signal, and the second oscillating circuit also has injection circuitry for injecting the first set of antiphase signals without a DC bias into the third output signal and the fourth output signal.

    Abstract: Data transfer devices and methods for transferring data between first and second circuits are disclosed. A data transfer device includes a first circuit having a plurality of data channels, wherein at least one of the data channels is an active data channel. A serializer has a plurality of inputs and an output, wherein the inputs are coupled to the plurality of data channels. The serializer is for coupling only one active channel at a time to the output. An isolation barrier is coupled to the output of the serializer, the isolation attenuates transients and passes the fundamental frequency. A second circuit includes a deserializer having an input and at least one output, the input is coupled to the isolation barrier, the at least one output is at least one active data channel.

    Abstract: 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.
