Abstract
一种多通道多载波收发机，包括：第一通道，用于传输第一载波；第二通道，用于传输第二载波；第一ADPLL，耦合至第一通道，用于为第一通道提供本振信号；第二ADPLL，耦合至第二通道，用于为第二通道提供本振信号；以及配置电路，分别耦合至第一ADPLL和第二ADPLL，用于根据第一载波和第二载波的组合信息，对第一ADPLL或者第二ADPLL进行配置。通过根据多个载波的组合信息，对锁相环进行配置，使得锁相环可以消除多个载波的频率牵引导致的杂散，提高了多通道多载波通信的可靠性；多个锁相环在版图上可以并排平行放置，不受限于锁相环的环路带宽，并且可以节约面积开销，而自身引入的面积代价很小。
