🇬🇧 Not a recommendation but an example of a good marketing strategy - here is an article written by a vice president of marketing of Lady Bug company. I like when marketing people have some technical basis and understand what they are talking about.

I did mention Lady Bug power sensors earlier on this channel - when wrote a list of affordable and portable devices. I've never touched their sensors but as I can see by the case quality and parameters, they are not worth recommending for professional use. But can be a nice addition to hobby lab I assume.

almost all the content I share here I read/watched, but this I recommend without testing. I believe I can trust RS 😄

?? I rarely give my negative comments, but my readers should be aware that not everything that I post (and you read on the internet) is 100% true. I post here good resources, but I do not agree with every word in the texts and videos.

In this #appnote by WE VIA pads are investigated. It is a good research idea, and it is done quite professionally. But I can't see the point in measuring smth up to 4 GHZ using angle PCB connectors and that strange DIY calibration (for those who think that calibration on the PCB eliminates connectors and microstrip line - no, it doesn't work like that). Also I doubt that simple MS line with those thermal antipads works well. And lastly - I couldn't find the PCB material description, but it looks to me as an FR4, and if it is -this research is useless.
