摘要
Embodiments of this application disclose an ODU and a transmit power control method for an ODU. The ODU includes a controller, a radio frequency processor, a waveguide channel, an antenna, a wave-absorbing block, a detector, and a motor controller. The controller is configured to obtain target transmit power, first transmit power, and a to-be-transmitted first radio frequency signal, and generate a control signal based on a difference between the target transmit power and the first transmit power. The radio frequency processor is configured to: perform frequency conversion on the first radio frequency signal to obtain the second radio frequency signal, and transmit the second radio frequency signal, where the second radio frequency signal is transmitted to the antenna through the waveguide channel. The wave-absorbing block has one end located in the waveguide channel and the other end connected to the motor controller. The motor controller is configured to drive, according to the control signal, the wave-absorbing block to move, so that the first transmit power is consistent with the target transmit power. In this way, according to the embodiments of this application, transmit power can be accurately adjusted, and the ODU can transmit a radio frequency signal at relatively low transmit power.
