For Apple, they are solving the biggest shortcoming on the iPhone, which is the problem of poor signal.
According to DigiTimes reports, Apple is increasing its investment in the design and development of its own antennas, because this is now more important in the 5G era, blindly using third-party solutions, inevitably there will be rollovers.
In fact, in this year’s iPhone 12, Apple has already taken action. For example, in the US market, it is equipped with Apple’s self-designed package antenna (Antenna-in-Package, AiP) to support millimeter waves (mmWave). .
The report mentioned that Apple will expand this usage ratio in the iPhone 13 series, and the RF front-end module (RF-FEM) is also included in Apple’s future independent plan.
Some people in the industry said that as the commercialization of 5G becomes stronger, it will drive more and more terminals to support this network, and the integration of RF-FEM is getting higher and higher. When mobile phones require more and more RF-FEM devices, RF-FEM must increase the integration level to control the actual size of the entire radio frequency system within an appropriate range.
At present, some manufacturers are already developing solutions that integrate low-noise amplifiers and switch modules, and Apple is also working in this direction, and mainly self-developed.
