It is just that the computation of Pfwd and Pref does not really produce real powers (though, again unfortunately, the dimension of the quantity produced is power). Funny how they can heat resistors both at the load end and at the source end when the source is equipped with a circulator+load. Incidentally, I've come up with a proof that there are no reflections at a voltage null in a homogeneous transmission line. Consider a 50 ohm lossless feedline. At a voltage null - rho = (50-50)/(50+50) = 0 i.e. no reflections in either direction -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
