Re: All of Apple's products depend on technology .... built here in the United States
And of course, a lot depends on what qualifies as "made" in the USA.
Most of the RF filter and amplifier modules (FEMs) are not CMOS ASICs that can be farmed off to the regular wafer bakers (TSMC, Global Foundries, etc) but GaAs, GaN, etc that give better power:performance ratio especially at these RF frequencies (e.g. 5GHz). The regular vendors of such (Skyworks, Broadcom (formerly Avago), Qorvo) have fabs in the USA but often perform the wafer-probe, module assembly and test in Asia either in-house or contracted out.
Within the module, there may be passive components that again are sourced from outside the USA - Murata, Panasonic, etc.
So, just because one of the die in the module was fabbed in the USA doesn't mean that the bulk of the manufacturing was performed there.
