    Hi everyone, I want to adjust the natural frequency of my NFC-circuit in order to optimize the perfomance. Maybe the question is too easy, but I'm new to the usage of a netwerkanalyzer. I want to do the Antenna tuning measurements as described in the application note in the appendix (see chapter...

    How do PKE keyless remotes work (inductive data transmission) and how would I "hack" one to make a transceiver?

    I'm wanting an undersea short-range remote (wireless button for dive thrusters) and induction seems perfect, so I bought a passive keyless car alarm to see how they work. I do understand that the car transmits an inductive signal, which the remote picks up (and then the remote does it's own...
