  • Publication number: 20100124210
    Abstract: A method for radio frequency transmitting and receiving beamforming using both GPS guidance and wireless access points is disclosed. The method comprises providing a wireless networking device with preloaded wireless access point locations; calculating a relative vector to an access point based upon at least one of the preloaded wireless access point locations; steering a transmitted beam with a sounding packet to the access point; calculating a channel condition by the access point; and sending a packet by the access point to the wireless networking device to establish a connection.

  • Patent number: 6140853
    Abstract: A digital phase detector and charge pump circuit system reset circuit and method resets a digital phase detector according to the charge outputs between the charge pump circuits and a following loop filter. The sensing circuitry emulates portions of the circuitry of the digital phase detector and charge pump circuit system and minimizes deadband time. Current mirror portions of the charge pump circuit alternate between p-channel and n-channel devices to regularize output voltage levels produced by the charge pump circuit system.

  • Patent number: 6052024
    Abstract: A direct detection receiver for a passive microwave and millimeter wave radiometric imaging system. The receiver includes a balanced switch low-noise amplifier (BSLNA). A front-end, low-noise amplifier (LNA) is inserted before the BSLNA to achieve a low-noise figure, as well as provide sufficient gain to minimize the input noise figure degradation due to loss of the BSLNA. A high-electron mobility transistor (HEMT) diode is used as a power detector. The front-end amplifier, BSLNA and diode are process compatible for monolithic integration.
