If an university wanted to develop an course about advanced electronics, it could do worse than just copying technical articles from the Analog Devices website.

Heh, my DSP II labs in undergrad were all done on Blackfin boards that were donated by an alum that went and worked for Analog Devices. At the time it was pretty rare for processors to include a bunch of the DSP-specific instructions like zero-overhead loops and multiply-and-accumulate so it was neat getting to play with “exotic” hardware :D

Nice report. I wish beamformer ICs were made for lower frequencies, but everything is targeting X-band and higher.

I guess there the digital beamforming is enough for many use cases.

The new availability of transceiver architecture of RF direct sampling or RF ADC/DAC can work from DC (0 Hz) to high frequency (GHz) is changing the landscape and now you can have beamforming at the lower frequency bands [1].
