  • Patent number: 9608707
    Abstract: Aspects for balancing power output on the plurality of antennas for the transmission of a transport block are disclosed. In accordance with the present disclosure, a transmitter may balance the power output on a plurality of transmit antennas in a multiple-input multiple-output (MIMO) system by having a precoded data block bypass a virtual antenna mapping of the overhead channels (e.g., control channels). Additionally or alternatively, the transmitter may balance the power output on the plurality of transmit antennas by applying an inverse mapping parameter during the precoding process to the transport block to generate a plurality of inverse mapped precoded data blocks. In some examples, the inverse mapping parameter may be an inverse of the mapping parameter. Thus, in accordance with the present disclosure, precoding a transport block may include selecting a precoding weight for each of the plurality of antennas from an unrestricted precoding weight set.

  • Patent number: 8824984
    Abstract: Examples are disclosed for outphasing power combining by antenna. In some examples, a device such as a wireless device may route a first signal to a first branch of an outphasing power amplifier system and route a second signal to a second outphasing power amplifier system. The outputs of the first branch and the second branch may be directly coupled to an antenna. The antenna may be arranged to operate as a power combiner for signals outputted from the first and the second branches of the outphasing power amplifier system. A power combined signal may then be transmitted from the antenna. Other examples are described and claimed.

  • Publication number: 20140242930
    Abstract: In one example, the present disclosure describes an antenna system with at least two linear antenna arrays, each having a plurality of antenna elements. Each array is designed to transmit and receive signals from different respective spectrum bands. The first antenna array and second antenna array are arranged to form one longer, combined linear array of antenna elements. In addition, at least one antenna element is shared between the first and second antenna arrays. In one example, the first antenna array is connected to a first RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the first antenna array and the second antenna array is connected to a second RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the second antenna array.

  • Patent number: 8811923
    Abstract: Methods and systems for an integrated voltage controlled oscillator (VCO)-based transmitter and on-chip power distribution network are disclosed and may include supplying bias voltages and/or ground to a chip utilizing conductive lines. One or more VCOs and low-noise amplifiers (LNAs) may each be coupled to a leaky wave antenna (LWA) integrated in the bias voltage and/or ground lines. One or more clock signals may be generated utilizing the VCOs, which may be transmitted from the LWAs coupled to the VCOs, to the LWAs coupled to the LNAs. RF signals may be transmitted via the LWAs, and may include 60 GHz signals. The LWAs may include microstrip and/or coplanar waveguides, where a cavity length of the LWAs may be dependent on a spacing between conductive lines in the waveguides. The LWAs may be dynamically configured to transmit the clock signals at a desired angle from a surface of the chip.

  • Patent number: 8781537
    Abstract: The semiconductor integrated circuit includes: a pair of antenna terminals; a rectifier; a source-voltage terminal; a shunt regulator; a series regulator. When the voltage of the inside source line rises to or above a first set voltage, the shunt regulator passes a pull-down current through a pull-down transistor. When the voltage of the inside source line drops to or below the second set voltage, the series regulator passes a pull-up current through a pull-up transistor. The first set voltage is set to be higher than the second set voltage in voltage level. With the semiconductor integrated circuit, the competition of actions of the two regulators is prevented. The semiconductor integrated circuit is arranged to work in contact and noncontact operation modes, and a stable source voltage can be supplied to an internal circuit thereof.
