  • PATCH ANTENNA
    Publication number: 20030201938
    Abstract: A patch antenna may be integrated into a mobile terminal by associating the patch antenna with a ground plane adapted to remove eddy currents and isolate the antenna from spurious electromagnetic signals. The patch antenna may comprise a kink. Together the patch antenna and ground plane form a surface on which other electrical components may be mounted, such as the transceiver circuitry of the mobile terminal.

  • Automatic Vcc control for optimum power amplifier efficiency
    Patent number: 6624702
    Abstract: The output power of a power amplifier is sensed, directly or indirectly. The sensed output power is used to control a bias circuit and a DC-DC converter that together control the power amplifier. This control circuit allows the power amplifier to be operated at high efficiencies as output power is changed.

  • Single output stage power amplification for multimode applications
    Publication number: 20030073418
    Abstract: The present invention eliminates the need for complex impedance networks or parallel amplification stages for multi-mode mobile terminals. A wideband power amplifier is configured to amplify signals in different frequency bands corresponding to different operating modes. The supply voltage of the wideband power amplifier is adjusted in light of the load impedance of radiating circuitry to achieve a desired output power for the respective operating modes.
