The quiet resurgence of RF engineering(atempleton.bearblog.dev)

Indeed, the dark arts of RF engineered components persist long after other technologies change.

Mostly, expensive tools became more accessible like TinySA, LiteVNA64 and NanoVNA.

For the amateur Ham hobby, it has been a bit of a golden age with <$50 rtl-sdr SDR kits. =3

Also for a student: I was at university 20 years ago and there was no possibility to "hack" RF devices. Right now, with less than 200€ (a NanoVNA and a good SDR), you can do almost everything.

It's also progress in components and compute that made insane things possible on a budget, that opened up new markets. Look at what this guy is doing https://hforsten.com/synthetic-aperture-radar-autofocus-and-...

But when will RF engineering pay 500k (common mid level SWE)?
mediaman 14 hours ago||
SWE are paid that because the industry makes so much money off advertising, and it marks the market for everything else.

It's more business model than skillset, because RF engineering is, in many ways, so much more technically challenging.

People who care about pay should mostly be thinking about how their potential employers make money. Do they have fat variable margins? Is there volume? Do I have the opportunity to impact those margins in some way? If you do, there's a good chance you can make good money, regardless of the actual technical challenge at hand.

For a lot of RF engineering, the answers are generally no, at least enough such that the general market isn't getting set at a high clearing rate.

Hardware engineers can get paid that, although it’s rarer. That said, there’s also a much broader base of hardware engineers than just the Bay Area… so cost of living is a lot lower, therefore salaries don’t need to be as sky high to compensate.

the difference is that RF engineers still have a salary 5 years later so that should probably be averaged in

4 out of the 5 FAANGs hire RF engineers so… now?

The demand for electronic warfare specialists is growing.

I agree broadly with the author but I think they miss the fact that American EE supply is not going to grow at e.g., 7% year over year. The infra for training new EEs, that is, the technical university, is losing the societial investment and public policy that made it possible.

Do you really think that the university is going to be the bottleneck? I have to imagine that sometime in the next decade, there's going to be some big reorganization to reflect the fact that you can now learn just as well OUTSIDE of a university context. Credentials are going to become less important, standardized testing and examination far more.

To just get started in RF you need to have a basic understanding of multivariate calculus, circuit analysis (including non-linear devices), systems and signals, electromagnetism, and semiconductor physics.

These are not topics you will just figure out on your own or "on the job".

I find it hard to see there being an alternative for the time being. I had access to tens of thousands of dollars of lab equipment during my EE degree. Probably worth the cost of tuition itself. Not to mention the commercial cost of simulation and cad software that we got for "free".

The other aspect is the professional engineering credentials. At least in Canada Engineering is a protected title. of which the easiest way to get your P.Eng is getting a degree through an accredited engineering program.

I have never seen an electrical engineer who managed to skip the university context let alone an RF electrical engineer. Zero. None.

There is a reason why so many people from engineering can switch to software while the converse almost never occurs.

In what way? RF test equipment is costly and so is building a home electronics lab.

Yes. I think American society will struggle to produce enough competent electrical engineers outside of the university system.

In my experience, very few people like learning the math needed to be competent at RF. It’s hard and exhausting and without a human connection most people are going to bounce. This isn’t like software where if you get it 80% right something still occurs.

I’ve worked with homeschoolers too, and unless they’re the small fraction of people for whom math comes naturally, they’re not going to study it on their own. But that’s exactly the audience one has to reach to grow the EE supply.

This person knows nothing about RF and is just another applications monkey. Without taking fields and waves you are at best a technician. Anyone who actually worked in defense knows that minicircuits is a notorious company that pays very poorly and has massive turnover. Many of the other defense/space RF subs are just the same. The author is just mangling all RF communications applications into one big ball. And of course the authors pathetic theory background means that RADAR is the only sensing application they "understand".

Read this https://www.microwaves101.com/encyclopedias/where-are-they-n... and tell me how well this next big surge is going to work out any differnt.

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.
