US iPhone 18 Pro Max Uses Qualcomm Snapdragon X80 Modem, Teardown Confirms

TechInsights’ teardown confirms the US version of the iPhone 18 Pro Max uses Qualcomm’s Snapdragon X80 modem, while the global models rely on Apple’s C2 modem; the US device reportedly includes a newly identified mmWave antenna module. Apple has not publicly explained the modem difference, and Qualcomm’s contract to supply modems through 2026 leaves room for questions about why only the US version uses Qualcomm. Performance tests will be needed to gauge any real-world differences between the X80 and C2.

Memristive 2D-hBN switches unlock reconfigurable GaN mmWave MMICs

Researchers demonstrate programmable millimetre-wave GaN MMICs with memristive switches made from hexagonal boron nitride (hBN) integrated directly in the BEOL. The on-chip BEOL switches operate up to 100 GHz with insertion losses around 0.3 dB and isolation above 15 dB, show two-week nonvolatile state retention, maintain stable on-state resistance up to 175 °C, and support linear power handling up to 18 dBm with an extrapolated 1‑dB compression point near 30.5 dBm. A compact 1T1M driver scheme achieves about 3,250 switching cycles; the work also demonstrates memristive-configurable attenuators, power dividers and programmable resonators on the GaN MMIC platform, pointing to more compact, cost-efficient reconfigurable RF front-ends for future 5G/6G mmWave systems.

iPhone 18 Pro: regional modem split, new A20 Pro packaging, and camera upgrade hints

Leaked data suggests the iPhone 18 Pro will use a region-based modem approach: U.S. models with Qualcomm mmWave hardware and other regions with Apple’s C2 modem. The A20 Pro may adopt WMCM packaging to enable more chip configurations. The rear main camera is expected to upgrade from Sony IMX-903 to IMX-905, with rumors of a possible variable aperture; China variants could gain eSIM support, reflecting regional product differences as outlined in Tata’s leaked files from a cyberattack.
