Great video from Analog Zoo – I especially appreciate videos that while informative on a technical level are also full of tips & tricks applicable to other designs!
RF filter design is a piece of cake these days thanks to computer design and simulation tools. But actually realizing the simulated filter response in the real world can be a completely different matter! This video provides an introduction to practical RF filter design by building, testing, and tweaking a 137MHz bandpass filter suitable for NOAA APT satellite reception.
