  • Transferable Wireless Communicator For Data And Voice
    Publication number: 20080123580
    Abstract: A communicator (110) that is transferable across different types of mobile devices (210) is disclosed. The communicator can simultaneously operate with both voice communication links (190) and data communication links (192), and with both voice and data information. The communicator may be transferred across various mobile devices, including but not limited to: mobile telephones (120), personal digital assistants (130), music players (170), radios, mobile computers (145), or devices that are a combination thereof. Some embodiments of the invention may be transferred while operating without breaking a wireless communication link. Data information may carried on a data link, such as a Bluetooth® link, a wireless Ethernet link, or an IEEE 802.11 link. Data information may also be carried on the voice link, such as a global system for mobile communication (GSM) link or a code division multiple access (CDMA) link.

  • Circuit and method for input side impedance matching of a power amplifier in an electronic device
    Patent number: 6747531
    Abstract: A circuit and method for input side impedance matching of a power amplifier in an electronic device. Specifically, the present invention provides an impedance transformer network that includes a negative resistor in series with a bondwire inductor. The network is placed in parallel with a signal source and synthesizes the source side impedance at the input of the power amplifier. The desired impedance is synthesized by selecting an appropriate value for the negative resistor and setting the reactance of the inductor equal to the capacitance of the electronic device at a required frequency of operation.
