You are all floundering about like fish out of water.

The ONLY way to predict the performance of a small resistor at UHF is to
treat it as a transmission line - starting with the simple dimensions of
length and diameter.

L, C and R, and short-circuit input resistance versus frequency
automatically drop into your laps with adequate ball-park accuracy.

As so-called engineers, if you can't measure it, such obvious arithmetical
techniques should already have been included in your elementary analytical
educations.

Spice (of which I have heard about only by reputation on newsgroups) is
useless unless one already knows what it's all about beforehand.

My criticism is not personal - only of the western world's educational
systems and insistent dependence on weapons of mass-destruction.
