Abstract

本申请实施例公开了一种ODU和ODU发射功率的控制方法，所述ODU包括：控制器，射频处理器、波导通道、天线、吸波块、检测器和马达控制器；控制器用于获取目标发射功率、第一发射功率和待传输的第一射频信号，以及用于根据目标发射功率与第一发射功率的差值产生控制信号；射频处理器用于对第一射频信号进行变频处理得到所述第二射频信号，并发射第二射频信号；二射频信号经所述波导通道传输至所述天线；吸波块的一端位于波导通道内，另一端与马达控制器相连，马达控制器用于根据控制信号带动吸波块移动，以使第一发射功率与目标发射功率一致。因此，本申请实施例可以对发射功率进行精确调整，并有利于ODU以较小的发射功率发射射频信号。
