I never understand why posts like this do not start with explaining what they are talking about. I am not familiar with the abbreviation RF and I'm not going on a research quest to guess which one the author could mean.

Thanks. The early 2000s wants their joke back. And just like it was back then, it's still not funny, just rude.

My criticism still stands. If I know what I am searching for, it's easy to find. But often enough have I seen authors use terms which can have multiple meanings and I would need to look at their definitions in parallel of the context of the article, just to understand what it's even about. No thanks, I'll just pick the next HN post instead.

You literally just have to search RF Engineering and the very first results will explain the term for you.
