高通發佈第二款5G晶片,Snapdragon X55 實現7Gbps高速率!

早在2016年,第一代 5G Modem 晶片 Snapdragon X50 發佈,而今日就公佈第二款的5G晶片 Snapdragon X55。主要特點是覆蓋5G到2G多模全部主要頻段,並支援獨立(SA)和非獨立(NSA)組網模式,也是全球首款實現7Gbps速率的5G晶片。

 

Snapdragon X55採用7nm單芯片內部結構,其中5G支援毫米波和sub-6 頻段,能為不同的 5G 電訊商作出最佳支援。理論傳輸速率方面,下載速度可高達 7Gbps,上傳速度最高3Gbps。4G網絡也得到升級,針對 5G 網絡的初期部署,X55更支援5G/4G 共享重疊頻譜。現時高通正在向各廠商提供 Snapdragon X55 5G晶片,預計最快將於2019年尾正式商用。

 

 

同時,高通還發佈全球首款宣布的5G 100MHz包絡QTM525、追蹤解決方案QET6100、集成式5G/4G功率放大器(PA)和分集模組系列,以及QAT3555 5G自適應天線調諧解決方案。QTM525是面向6GHz以下5G和LTE的全新單芯片14納米射頻收發器,配合5G晶片的X55,可使用於8MM輕薄外形的手機,使5G網絡手機與4G網絡手機尺寸相當。
