Impedance Controlled PCB Features {Microstrip Line & Coplanar Waveguide with Ground} (034)

This video is all about the basics of creating impedance controlled features on a PCB.
You can create transmission lines on your PCB that mimic coax!
There are many, many configurations of impedance controlled features on PCBs.
I will address two specific kinds:
Microstrip Lines
Coplanar Waveguide with Ground (don't let this name scare you ... it's just a name)

Thank you for your professional explanation, which saved my master‘s career. Because I major in material engineering, I didn’t know anything about the transmission line design at all, but after watching your video, I had a preliminary understanding of CPW (coplanar waveguide). Now I can design my material as CPW. Thank you very very much.😊

WOW! I am so glad that my video was a big help to you! You are very, very welcome! 🙂

[@dennisqwertyuiop]

very good,,thanks for your time

[@eie_for_you]

My pleasure!

[@asif530]

Awesome video. Absolutely well done and good results with your experiments. This is so useful ..

[@eie_for_you]

Thanks, man! The good news is, it is in reach of most every experimenter thanks to the on-line calculators.

Really fantastic explain,and can see you know what you do. And yes...question. How to calculate stripline for 2 transistor lin. amplifier,like in some linear is?

[@eie_for_you]

Many, many factors here. My method of operation? Review documents like this one: drive.google.com/file/d/1iuPO1tRLOUhiJBPB0SK6KoM4ijQ_TDX3/view?usp=share_link to determine what exactly to call what you are trying to design because nomenclature is *everything* in this business. Then I would look for an on-line calculator to calculate the necessary stuff. I'd create a quickie, sanity check experimental version, modify your design as needed per the experiment, then create the final design. You can kinda see my process in this other video of mine dealing with an impedance controlled PDB design (in the end): kzbin.info/www/bejne/bWmcgWSulq-Wlbc
