How many of you guys are RF Filter design engineers?
Study hard, then get a job that does RF filter design. Somtimes it’s by luck, i.e. that’s the job that was available and you happened to have taken a course in filter design and got an A in it. Getting an A in EM Theory also helps. RF filters are still mostly analog today and requires both math, science and lots of art. Other types of filters, i.e. base-band, are all mostly relegated to digital designs these days. The higher the frequency, the more challenging the design. There are some RF filters, i.e. mmwave that looks like a bunch of traces, i.e. no real components on them at all and then there are waveguide filters that are all mechanical dimension specific with some magnets and screws in them. I think that the top of the heap of RF engineers are antenna design engineers (note that an antenna is a special kind of filter). They are a special breed. There could be like a 1,000 engineers on a project from systems engineers, to hardware circuit designers, to GUI software, to embedded s
