    First of all, I hope this is in the right subforum here.
    I'm trying to simulate a RF-Transmitter circuit for my semester project at university using Multisim. Now of course I would like to use a model of the actual transistor I'm using in the real circuit, which is a BFP720F by Infineon.

    I've attached the SPICE model as provided by the Infineon.

    If I import it as-is, I get error messages about "invalid node identifier '<4>'" (I've translated that from German, so it might not be exactly this message in the english version).

    So I tried replacing all the '<4>' with '4', which seems to help, but now the error is "Temperature adjusted parameter 'VJC(PC)' is negative" and "Incorrect use of model parameters"... Now I really don't know what to make of this.

    Is the provided model in a wrong format? Can I somehow get it into the right one so I'm able to use it?

    By the way, I've also posted this question in the NI support forum, but that doesn't seem very active so my hopes aren't too high to get an answer there... So I really hope that there's someone here with some experience in Multisim that could help me out.

    Thank you very much in advance!
