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

- lormayna 6mo agoAlso 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.
- Joel_Mckay 6mo agoIn general, some SDR offer phase-locked quadrature encoder/decoder RF front-ends. https://www.mouser.com/c/?marcom=120135054 https://www.mouser.com/c/?marcom=120135054 Combined with a good directional coupler and GPSDO, people do build very high-end pieces of equipment. Not user friendly for most students, but removes a lot of traditional DSP complexity. Current design limits on bit-resolution and bandwidth are usually just people avoiding getting hit with export restrictions. The Pluto SDR rich software ecosystem is likely a better option for students: https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/adalm-pluto.html https://www.analog.com/en/resources/evaluation-hardware-and-...
