"Oh jeez, sounds like a skin depth problem. The assemblers love it, they say the gold plating is 'hard as a rock'!" There was a language barrier, don't know if they were able to understand the plating specification. Except we did go to a new thin film vendor. "Hey Bert, the gain on that new design stinks, what's the problem? Did you change anything from the last design?" Often "experts" start in on the discussion, and it goes like this. Every time microwave engineers encounter a new frequency band or a new metalization scheme, there is some question over RF losses in transmission lines such as microstrip. The topic of skin depth is a misunderstood one, but we are going to end that right here and now. The mystery of skin depth - a timeless story The mystery of skin depth - a timeless storyĪbout that power line. Here is a clickable index for this web page: There are approximately 40 micro-inches in one micron, that's close enough when you are dealing with plating. Regarding skin depths and thin film thicknesses, if you want to convert from microns to micro-inches exactly, divide microns by 0.0254. Why? because there are no popular units of bulk resistivity in the English system. You need JavaScript enabled to view it.īy the way, we use the metric system for this discussion, and in the download.

We know, because we did the search! Along with this discussion we offer a download that calculates equivalent RF sheet resistance for metals that have up to three different layers. This is one of the best discussions of skin depth effects anywhere, including the entire searchable microwave paper collection of the IEEE. The skin depth equation is as relevant to microwave engineering as Newton's law (F=mA) is to physics. Skin depth is one of the most fundamental issues in microwave engineering, but it also affects lower frequencies, even 60 cycle AC power. RF sheet resistance (first read about "DC" sheet resistance here) Why are there two conductors on this high power line?
