Impedance Matching In Your Designs

Important note:
Taking from a reference design is a good starting point but YOU should tune it to your purpose. Results may vary from what you have on your board and such, the components, stack up etc..
----
A topic I had struggled in the past was impedance matching, what are the components between an antenna and the micro? What is its role? How do I know if they are correct? How do I implement such a thing?
Today we go over briefly on this topic of Impedance Matching to get you started and not waste time in your designs when incorporating an RF line of some sort.

Thank you! Glad it’s useful!

Thank you so mich for this video!

[@WinterCircuits]

Very welcome!

Very nice

matching for maximum power transfer and matching for minimum reflection are not the same. had to figure that out the hard way. maximum power transfer requires the load impedance to be the komplex konjugate impedance of the source, minimal reflection requires them to be the same. so only one criterion can be met ( unless you work in dc)

Thanks for sharing that, its much appreciated and can see the confusion it causes, upon reading more I see the error in what I thought. Thanks for pointing it out!

@@WinterCircuits as long as you work in just real resistances, so no reactances, they actually are the same thing, manufacturers will tell you that their products are purely resistive but in reality, most of the time they are not ;)
