In the dismantling of the Apple iPhone13 series, we saw the inherent strength behind the powerful iPhone13 series. In addition to the new Apple A15 bionic chip, there is also a very powerful 5G baseband chip on the back-Qualcomm Snapdragon X60. It is also the baseband chip used in this year's Android chip Snapdragon 888 and Snapdragon 888 Plus, and it is likely to be the strongest 5G mobile terminal baseband chip solution on the market.
The advantage of the Snapdragon X60 5G baseband chip is by no means simply supporting a download rate of up to 7.5Gbps and an upload rate of up to 3.5Gbps, but to achieve the current industry-leading 5G frequency band compatibility.
Since the Apple iPhone13 series will be adjusted according to the network standard of the sales area, it has very strict requirements for the compatibility of the network frequency band of the baseband chip. Taking 5G network as an example, it is currently divided into two frequency bands: Sub-6GHz and millimeter wave (mmWare). The former has wide signal coverage and strong resistance to blocking, but the network speed is quite different from the peak speed of 5G networks. The frequency band technology standard adopted in the main stage is suitable for the rapid advancement of the initial construction of 5G network. The latter is fast, large in capacity, and good in directional transmission, but its coverage is small and easily blocked. It is the 5G frequency band dominated by the United States and is suitable for 5G coverage in some large cities. Regardless of which 5G network standard is selected, mobile phone terminal products equipped with the Snapdragon X60 5G baseband chip can satisfy.
In this regard, the Snapdragon X60 5G, as the third generation 5G baseband chip following , Snapdragon X50 and X55, is the third generation 5G baseband chip of Qualcomm . It is also the world’s first 5G baseband chip that supports aggregation of all major frequency bands. It supports 5G SA, NSA dual networking, supporting millimeter wave, Sub-6GHz (FDD/TDD), 5D TDD and FDD carrier aggregation and dynamic spectrum sharing, further improving energy efficiency, throughput, antenna coverage performance, and meeting the high requirements of Apple iPhone13 series on the network . At the same time, in order to deal with the high power consumption problem brought by 5G networks,The Snapdragon X60 5G baseband uses the most advanced 5nm process technology, which effectively reduces the power consumption and heat generation of the baseband chip, which is conducive to extending the overall battery life of the iPhone13 series.
Take the National Bank Apple iPhone13 (A2634) equipped with the Snapdragon X60 5G baseband chip as an example. Its 5G NR bands are n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n30, n38, n40, n41, n48, n66, n77, n78, n79.

The above 5G frequency bands are all Sub-6GHz frequency bands, including China Mobile n28, n41, n79 5G frequency bands, China Telecom and China Unicom n78, and China Radio and Television's n28 and n79 (both frequency bands are jointly built and shared with China Mobile), fully cover the 5G frequency bands that have been approved for commercial use in China. Among them are 3.5GHz (n78) and 700MHz (n28), which are known as the golden frequency bands. The latter's ultra-wide coverage is conducive to the promotion of 5G networks in remote areas and realizes broader coverage of 5G networks.
The US version of iPhone13 (A2482) also uses the Snapdragon X60 5G baseband chip, but combined with the local 5G network deployment, the US version of iPhone13 supports n1, n2, n3, n5, n7, n8, n12, n20, n25, In addition to the sub-6GHz frequency bands such as n28, n29, n30, n38, n40, n41, n48, n66, n71, n77, n78, and n79, support for the n258, n260, and n261 millimeter wave frequency bands has also been added. Among them, n260 (39GHz) is the millimeter wave 5G frequency band of local operator AT&T, and n261 (28GHz) is used by T-Mobile and Verizon .Whether it is Sub-6GHz or millimeter wave 5G frequency band, the Snapdragon X60 5G baseband can be perfectly supported in one step.

was also seen in the disassembly of the US version of the iPhone13 series by foreign media techinsights. In addition to the Snapdragon X60 5G baseband, Apple has further adopted the RF antenna module from Qualcomm and matched it with the iPhone13 series. With the new antenna design, this year’s iPhone 13 series still maintains excellent mobile network performance.
With the addition of the Snapdragon X60 5G baseband, terminal mobile phone manufacturers such as Apple can flexibly adjust the network format of their products according to the network differences in the sales area. While reducing the technical difficulty and accelerating the speed of research and development, it can also ensure the performance of terminal products. Possess leading network performance to meet the long-term development needs of global 5G networks.
