ARLA/CLUSTER: Prototipos rápidos de filtros de RF

[João Costa > CT1FBF]

Rapidly prototyping RF filters

*Sebastian Holzapfel VK2SEB* has released a guide to simulating microstrip
filters in QUCS and prototyping them with copper tape on blank FR4 sheets

These super-cheap materials are good up to a couple gigahertz, as you'll
see in the video.

Following a quick real-time demonstration, I simulate and build 2
microstrip filters, a 1GHz stepped-impedance LPF, and a 10GHz end-coupled
BPF.

2:05 - 1/4 wavelength stub build & tests
3:46 - Radial stub build & tests
4:18 - Stepped impedance microstrip LPF design
6:42 - Stepped impedance microstrip LPF build & tests
9:10 - Trimming the stepped impedance LPF
10:26 - Brief tutorial on synthesizing filters in QUCS
14:51 - Synthesizing a 10GHz end-coupled microstrip BPF
18:33 - 10GHz end-coupled BPF build & tests
