While you could simulate even at THz with LTspice, that doesn't mean the results will be accurate, unles the simulator was built for such frequencies. There are lots of apparently counter-intuitive things happening there. One consequence of these is the ability to model the diode with an RLC circuit (for small ranges of signal). I'd say try it and see if it fits what you're searching for. | |

@aconcernedcitizen Cjo is a different parameter which is also listed in a different column in the table. Cjsw is described as a Sidewall Cjo, is it the other name for Cjpar parameter in the table from datasheet?

Their model doesn't have an "Cjpar" component. I'd say this one is worth a call to a Macom apps engineer. | |

Are you sure it's not Cjo (there's also Cjsw, but that's not what you're after)? Even if it isn't, that's what you should use (see the help in LTspice > Circuit Elements > D. Diode, the 2nd table.
