CNC Milling Radio Microstrip Filters

Microstrip or distributed element filters and an elegant solution to a complex problem. How do you filter out parts of the radio spectrum you don't want, without having to manufacture accurate capacitors and inductors at small scales. They also have the advantage of being relatively easy to manufacture by simply milling the right pattern on regular PCB material. While they aren't perfect, they work well for frequencies between 400-1800 mhz.

In this video we cover the basics of CNC milling and how some of these filters are made.
