Real World RF Filter Design and Construction
We bet when [devttyS0] made his latest video about RF filter design (YouTube, embedded below)vi, he had the old saying in mind: in theory, there’s no different between theory and practice, but in practice, there is. He starts out pointing how now modern tools will make designing and simulating any kind of filter easy, but the trick is to actually build it in real life and get the same performance. You can see the video below.
One of the culprits, of course, is we tend to design and simulate with perfect components. Wires have zero resistance, capacitance, and inductance. Inductors …read more
