  • Publication number: 20160278141
    Abstract: A disclosed wireless tunneling system tunnels communications between two processing apparatuses through a wireless link, while maintaining compliance of the communications between the two processing apparatuses with at least two different wired communication protocols. In one embodiment, the wireless tunneling system includes two wireless tunneling apparatuses that communicate with each other through the wireless link. A local wireless tunneling apparatus is coupled to a local processing apparatus through a wired connection and a remote wireless tunneling apparatus is coupled to the remote processing apparatus through another wired connection. The two processing apparatuses may communicate with each other through the wireless link using the two wireless tunneling apparatuses as if the two processing apparatuses were connected through wired connections.

  • Patent number: 8928411
    Abstract: Embodiments of the invention are generally directed to integration of signal sampling within a transistor amplifier stage. An embodiment of an apparatus includes a amplifier stage including a transistor to receive a source signal and produce an output signal, wherein the transistor includes multiple fingers for at least a first electrode of the transistor. The amplifier stage uses connections to some of the fingers of the first electrode for production of the output signal, and uses one or more other fingers for the first electrode of the transistor for a separate function from the production of the output signal.

  • Patent number: 8229352
    Abstract: A device has an RF mixer, an IF mixer module, a single synthesizer, a frequency divider, a single side band mixer and a frequency quadrupler. The single synthesizer generates a signal to the IF mixer module, the frequency divider, and the single side band mixer. The single side band mixer mixes signals from the single synthesizer and the frequency divider. The frequency quadrupler receives the output of the single side band mixer. The RF mixer is coupled to the frequency quadrupler and the IF mixer module.

  • Patent number: 8170522
    Abstract: A circuit features a balun having an unbalanced input and a balanced output, and a differential coupler having a symmetrical structure about a center axis. The differential coupler has a differential input and a differential output, the differential input being coupled to the balanced output of the balun. An impedance element is coupled to a circuit node of the differential coupler at a point along the center axis. Other embodiments are also described and claimed.

  • Patent number: 7904117
    Abstract: A method and apparatus is disclosed herein for wireless communication with adaptive beamforming. In one embodiment, the apparatus comprises a processor, a radio frequency (RF) transmitter having a digitally controlled phased array antenna coupled to and controlled by the processor to transmit content using adaptive beamforming, and an interface to a wireless communication channel coupled to the processor to communicate antenna information relating to the use of the phased array antenna and to communicate information to facilitate playing the content at another location.
