The enclosure costs will be negligible, but the PCB will not be. These phased array antenna designs from SpaceX and Amazon are some of the most complex PCBs ever theorized, with many dozens of layers and requiring manufacturing processes that do not currently exist at scale.
- madengr 6y agoNot really. I just built a 256 element array covering 2 octaves BW. The feed board is seven layers. Arrays are lots of repetitive circuitry. I think the impressive part are getting microwave RFIC for pennies. Now this PCB is crazy: https://youtu.be/nurL3N1Etuc https://youtu.be/nurL3N1Etuc
