Is there an LTSpice model for ADL5205? If not, could one be generated?

Hi,


So far as I can see, the only simulation tools available for ADL5205 are S-parameters, which include the 50 Ohm test setup as well as the 10 Ohm internal output impedance. Is there an LTSpice model available for this part, or simulation S-params without this additional resistance?


Thank you

    Hi grawl,
    

    This is the feedback I have from the RF team “We did a few LTspice models for log detectors but I don’t see it as an RF tool at all. If you really tried, I bet that you could make and simulate…

    Hi grawl,
    

    This is the feedback I have from the RF team “We did a few LTspice models for log detectors but I don’t see it as an RF tool at all. If you really tried, I bet that you could make and simulate a model for an RF amplifier but it’s just not the appropriate environment. LTspice is not just a dc tool. It’s also great for ac analysis, just not RF analysis.”

    LTspice tool is that it is more of a dc accurate, instrumentation type of tool.  It is incredibly useful for switch mode power supply design.

    In summary, I'm sorry that no LTspice model for ASL5205 will be made available in the library.
