Publication number: 20240088840Abstract: An electronic device may include wireless circuitry with a processor, a transceiver circuit, a front-end module, and an antenna. The front-end module may include amplifier circuitry such as a low noise amplifier for amplifying received radio-frequency signals. The amplifier circuitry may operation in different modes based on its operating environment. Accordingly, the amplifier circuitry may include multiple amplifying cascode stages coupled in parallel, some of which may be selectively enabled. The amplifier circuitry may include an intermodulation distortion suppression circuit coupled to an amplifying cascode stage and an n-path filter coupled to another amplifying cascode stage. One or more of these amplifier circuitry portions may be active depending on its operating mode.Type: ApplicationFiled: July 26, 2023Publication date: March 14, 2024Inventors: Christian Tanzer, Julian Zuber, Matthias Voelkel, Dominic Koehler, Harald Pretl, Joonhoi Hur, Rastislav Vazny

Publication number: 20240080063Abstract: Systems and methods combine a test signal with a wanted (downlink or uplink) signal at an input of a duplexer of a communication device, and receive the test signal at an output of the duplexer. The test signal may include a radio frequency signal having less power than the wanted signal to avoid interference, or a digital signal that is added to or extracted from the wanted signal when the wanted signal does not have a radio frequency. A processor of the communication device causes the duplexer to operate in a tuning state (e.g., to transmit signals having a transmission frequency and receive signals having a receive frequency). The measurement system determines a difference or ratio in power between the test signal at the duplexer output and the duplexer input, and adjusts the tuning state based on the difference or ratio (e.g., to decrease or minimize the difference or ratio).Type: ApplicationFiled: September 7, 2022Publication date: March 7, 2024Inventors: Christof Pfannenmüller, Dominic Koehler, Julian W Zuber, Oliver Georg Dorn, Bjoern Lenhart, Harald Pretl, Rastislav Vazny, Christian F Tanzer

Publication number: 20210279606Abstract: Systems and methods are described for adding new attributes to entities of a knowledge base. A plurality of correlations may be identified between the new attribute and existing attributes of the entities using a rule-based model, such that attribute rules may be associated with each identified correlation exceeding a predetermined confidence threshold. An unstructured data model may then be applied to the knowledge base to identify unstructured data associated with each entity of the plurality of entities correlated to presence of the new attribute. Then a meta learner model may be applied to identify weights for each attribute rule and the identified unstructured data. After the weights have been set for the meta learner model, the meta learner model may then be applied to each entity in the knowledge base to accurately identify entities having the new attribute.Type: ApplicationFiled: March 9, 2020Publication date: September 9, 2021Inventors: Vijay Srinivasan, Christian Koehler, Hongxia Jin
