  • Publication number: 20230370382
    Abstract: In one embodiment, an offload platform is an compute platform, adjunct to a router or other packet switching device, that performs packet processing operations including determining an egress forwarding value corresponding to the next-hop node of the packet switching device to which to send an offload-platform processed packet. The offload platform downloads forwarding information from the router, and augments it, such as, but not limited to, representing interfaces of the router as identifiable virtual interface(s) on the offload platform, and including each of one or more next-hop nodes of the router represented as an identifiable virtual adjacency and identifiable tunnel (e.g., identified by the egress forwarding value). In one embodiment, the egress forwarding value is an Multiprotocol Label Switching (MPLS) label or Segment Routing Identifier. The router identifies packets of certain packet flows to send to the adjunct offload platform, rather than processing per its routing information base.

  • Publication number: 20230344387
    Abstract: Envelope tracking systems for power amplifiers are provided herein. In certain embodiments, an envelope tracker supplies power to a power amplifier that amplifies an RF signal. The envelope tracker includes a multi-level switching circuit that generates an output current based on an envelope signal indicating an envelope of the RF signal. The envelope tracker further includes a combiner that combines a DC voltage with the output current of the multi-level switching circuit to generate a power amplifier supply voltage for the power amplifier. Accordingly, the output current of the multi-level switching circuit and a DC voltage are combined to generate the power amplifier supply voltage. Implementing the envelope tracking system in this manner can provide enhanced efficiency and/or higher bandwidth relative to an envelope tracking system in which a multi-level switching circuit directly outputs a power amplifier supply voltage.

  • Publication number: 20230344452
    Abstract: Radio frequency front-end systems with filter reuse. In certain embodiments, a front-end system includes a filter, a low noise amplifier (LNA), and a switch interposed between the filter and an input to the LNA. In a first state of the switch, the filter serves to filter a radio frequency signal that is amplified by the LNA. The front-end system further includes a power amplifier that is coupled to the switch. Additionally, in a second state of the switch, the filter serves to filter an amplified radio frequency transmit signal provided by the power amplifier. Accordingly, a filter along a receive path of the front-end system is reused for transmit.
