I have been using this software for years, but still I learned a lot by watching these videos: AC Analysis. How to change the values of the things you are measuring. Even something as simple as drawing a wire right through a component to get leads on both sides. This is really useful stuff. <\/b><\/div>\n<div><b><br \/><\/b><\/div>\n<div><b>RF Man goes through the whole design of the RF amplifier. He describes how to use LTSpice to determine input and output impedances (he does this with a NanoVNA in another video). He talks about the use of negative feedback, and temperature compensation. There are swamping resistors as Q killers. This is all great, real-world stuff. <\/b><\/div>\n<div><b><br \/><\/b><\/div>\n<div><b>Especially useful for me was his presentation on how to do &#8220;two tone&#8221; IMD tests.<\/b><\/div>\n<div><b> <\/b><\/div>\n<div><b>There is a lot to learn here. RF Man has a really wonderful way of explaining complex theory, and demonstrating complex tests.
