As electronics is increasingly more talked within the military action context, I feel I have to write that PRC defence industry is far more starved off components for which they cannot procure a consumer market analogue than ones for which they can.
Any generic smartphone SoC has enough processing power nowadays, sufficient for any imaginable guidance task, including computational radar imaging – something that once required a supercomputer. An MCU will compute you a missile trajectory from any point on the earth to another, and a recent smartphone SoC will be able to do a realtime imaging radar with every computational enhancement trick.
However, PRC cannot build the said imaging radars without RF and analog chips. Shahed drones cannot get guidance without high grade RF PCBs, and MEMS sensors. TV guided drones cannot see anything without specialist image sensors. All off that stuff is being relatively low volume, and has to be 99% imported by PRC, Russia, NK, Iran.
PRC can make an average SoC you put into a TV, but not 100 Ampere VHF/UHF transistors for radars, and military radios.
RF foundries, specialist RF materials/components, niche analog nodes, advanced MEMS, non-consumer grade imaging sensors – almost all is still exclusively Western.
