Apple Extends Broadcom Chip Deal to 2031, Delaying Full In-House Modem Shift

Q: What key technology does Broadcom have that even Apple, after spending billions, can't replicate for its iPhones before 2031?

The key capability is Broadcom’s radio and connectivity stack for iPhones, especially custom RF front-end chips, plus Wi‑Fi and Bluetooth silicon that works at Apple’s scale and performance requirements. The Reuters-reported extension through 2031 matters because Apple’s in-house C-series effort is focused on the cellular modem itself, not the full surrounding radio system. A modem is only one part of the wireless chain. Broadcom supplies the chips that handle radio-frequency functions and short-range connectivity, areas where performance, power efficiency, interference control, carrier certification, and global band support are extremely difficult to match. Apple has made progress with its own modems, starting with the C1 and moving toward the C2 with mmWave support. But the new Broadcom deal signals Apple still does not expect to replace Broadcom’s custom RF, Wi‑Fi, and Bluetooth components across iPhones before 2031. That suggests the hard-to-replicate advantage is not just a single chip, but Broadcom’s deep IP, engineering know-how, and validated designs in wireless connectivity. In practical terms, Broadcom’s edge is its mature RF front-end and connectivity technology: the custom radio chips that help iPhones connect reliably to 5G networks, Wi‑Fi networks, and Bluetooth devices while meeting Apple’s battery-life, size, and global compatibility targets. That is the part Apple, despite years of investment, still appears unable to fully internalize on its own timeline.

Broadcom said Monday it expanded its custom-chip partnership with Apple through 2031, a sign Apple will keep relying on outside radio components for years.
That timeline suggests Apple does not expect to complete a full transition to its own cellular modems before 2031, despite rolling out its first C-series modem chips in recent iPhones and iPads.
Apple’s C1 and C1X chips improved power efficiency but lacked mmWave 5G, leaving some devices dependent on third-party solutions while the expected C2 in the iPhone 18 Pro line adds that support.
Broadcom shares rose nearly 4% in premarket trading as the deal reinforced its long-running role supplying Apple with radio-frequency, Wi-Fi, Bluetooth and other networking chips.
