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. ---- Reg. |
