5G MIMO 无线电：射频和定时

概览

随着对蜂窝服务带宽的要求越来越高，全球对 5G 多输入多输出（MIMO）解决方案的需求也越来越高。 该系统实现了 5G MIMO 所需的射频链和时钟树。

系统优势 ：

  • Sub-6GHz 器件面向小信号射频链，从 RF 天线到 ADC 来接收信号（Rx），以及从 DAC 到 PA 来传输信号（Tx）
  • 同类产品中最佳的高级定时产品具有极低的相位噪声和杂散抖动
  • 支持输入时钟冗余、中高频时钟扇出、JESD204B/C 和 IEEE 1588，以增强通用公共无线电接口（eCPRI）
  • 提供单芯片同步和时钟生成
  • 大规模 5G MIMO
