Shuw Guann Lin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Wireless transmitter/receiver utilizing DSSS technology
    Patent number: 6366764
    Abstract: A wireless LAN RF module uses parasitic element compensation devices in an antenna select circuit to improve port isolation. In addition, various combinations of RC filter networks and spurious radiation attenuators are incorporated into the Quad Demod/Mod and Synthesizer ;/circuits to provide suppression of EMI susceptibility and radiation throughout the RF module.

  • Antenna selector switch
    Patent number: 6205171
    Abstract: A wireless LAN RF module uses a low power transistor switchable voltage divider circuit to control the bias input of a GaAs MESFET output power amplifier. This bias control circuit provides stable, high speed on-off switching of the power amplifier stage by applying low power bias voltages to the MESFET gate input, rather than by interrupting the high power MESFET drain to Vdd circuit.
