  • Patent number: 11881818
    Abstract: Envelope tracking schemes for Doherty power amplifiers are provided herein. In certain embodiments, an envelope tracking system includes a carrier amplifier that amplifies a first radio frequency signal, a peaking amplifier that amplifies a second radio frequency signal corresponding to a delayed version of the first radio frequency signal, an envelope tracker that generates a first power supply voltage that powers the carrier amplifier, and a delay circuit that delays the first power supply voltage to generate a second power supply voltage that powers the peaking amplifier. The envelope tracker controls a voltage level of the first power supply voltage to track an envelope of the first radio frequency signal. Thus, supply modulation is used to achieve gains in linearity, efficiency, and/or other performance metrics.

    Abstract: Radio frequency (RF) communication systems with interference cancellation for coexistence are provided herein. In certain embodiments, an RF communication system includes a transmitter including a power amplifier that amplifies an RF transmit signal, a receiver including a low noise amplifier (LNA) that amplifies an RF receive signal, and an interference cancellation circuit that selects a bandpass filter from a plurality of bandpass filters to filter the RF transmit signal after amplification by the power amplifier. The selected bandpass filter operates in combination with a controllable gain circuit and a controllable phase circuit to generate an analog interference cancellation signal that is injected into the receiver to compensate the RF receive signal for interference arising from the transmitter.

  • Publication number: 20230421554
    Abstract: Examples for identification and authentication of hardware. Techniques may include receiving a node identifier during an initial phase of the node. The node identifier may include an initial unique identifier of the node. The node may receive a latest change identifier during a phase change of the node, wherein the phase change may cause a hierarchical change of the node. The latest change identifier is configured to incorporate a latest unique identifier corresponding to a latest system and one or more unique identifiers corresponding to one or more earlier systems of the node. Further, responsive to the reception of the latest change identifier, delete an earlier change identifier, and the node may send the second change identifier to a management service, in response to a request for authentication of the node by the management service.

  • Patent number: 11855663
    Abstract: The radio frequency front-end systems herein include modules having bandwidth controllable components, such as amplifier and filters. By implementing the modules with bandwidth control, the same module can be used for operation of multiple frequency bands including a first frequency band and a second frequency band. Thus, when implementing features such as carrier aggregation, multiple-input multiple-output (MIMO), and/or sounding resource signaling (SRS) for supporting the multiple frequency bands, the total number of modules used can be reduced and/or additional feature support can be provided compared to an implementation in which each module supports a single frequency band.
