Publication number: 20230420996Abstract: A wireless power transmitting system includes a power amplifier comprising a plurality of measurement points and a power amplifier controller integrated circuit (IC). In some embodiments, the power amplifier controller IC performs synchronization of the various components of the power amplifier, conducts impedance and temperature measurements at the measurements points, determines if a foreign object is within the transmission range of the wireless power transmitter, and decides if a shutdown of the power amplifier is needed. In some embodiments, the power amplifier controller IC determines through a transmitter controller IC, the presence of a foreign object within the transmission range and adjusts the power transmission to one or more receivers.Type: ApplicationFiled: June 27, 2023Publication date: December 28, 2023Inventors: Cesar A.

Publication number: 20120309325Abstract: Disclosed are various embodiments for an extremely high frequency transceiver employing a baseband module and a radio-frequency module. The baseband module and the radio-frequency module are connected by a coaxial cable. The coaxial cable carries a multiplexed signal that may include a direct current component, a clock reference, a control signal, and an intermediate frequency signal. The control signal encodes one or more commands for controlling the operation of the radio-frequency module. Multiple radio-frequency modules may be employed in some embodiments.Type: ApplicationFiled: December 8, 2011Publication date: December 6, 2012Applicant: BROADCOM CORPORATIONInventors: Nick Carbone, Sean Nicolson, Koji Kimura, Brima Ibrahim, Jason A.
