  • CC1101: Impedance matching of antenna on CC1101

    TI Thinks Resolved
    Part Number: CC1101 We have a CC1101 for 868MHz communication in a circuit we are currently revising and the matching therefore needs to be tuned again. The person who was in charge of the RF circuits now works somewhere else and I am therefore trying…

  • CC1101: 433MHz TPMS migrating from Async Serial Mode to FIFO Mode

    Part Number: CC1101 Tool/software: Hello, I've recently started using a CC1101 to read 433MHz TPMS sensors. I have the ability to read signals and parse them correctly using the CC1101 in Asynchronous Serial Mode, which honestly was no easy feat…
