Rapid Prototyping RF Filters with Tape & QUCS

An overview to mimicing microstrip filters in QUCS as well as prototyping them with copper tape on empty FR4 sheets. These super-cheap products are excellent as much as a pair ghz, as you’ll see in the video clip.
Complying with a fast real-time demo, I develop as well as imitate 2 microstrip filters, a 1GHz stepped-impedance LPF, and also a 10GHz end-coupled BPF.
