Shahriar Shahramian performs an in-depth RF analysis and teardown of the Starlink satellite dish, examining its phased array architecture and integrated circuits.

In this episode Shahriar takes a detailed look at the Starlink Satellite Dish. The dish was kindly sent by Ken who has done his own initial teardown here: youtu.be/iOmdQnIlnRo The dish is analyzed layer by layer from the radome down to individual integrated circuits. The RF design, system architecture and many aspects of the overall product are described in details. An X-Ray of the RF stack is also shown which further explores the design of the array. www.TheSignalPath.com www.YouTube.com/TheSignalPath​ www.Patreon.com/TheSignalPath

It's a phased array, it uses those many little chips to do "beam steering". Check out this video by The Signal Path (a Bell Labs expert!) doing a teardown and explaning parts of it: link to this video

On “Setting up Starlink”

There’s a pretty crazy amount of electronics in the dish. They are likely selling it at well below cost at present. Teardown showing PCB at: link And more detailed RF analysis at link to this video

Starlink receivers are actually very complicated. They make use of a bunch of high-end FPGAs and a bunch of other expensive and uncommon components. See this teardown: link to this video .
