But radiofrequency (rf) front-end imperfections can lead to the loss of channel reciprocity, which will invalidate the advantage of TDD systems.
但是射频器件的非理想特性将导致信道互易性的丧失,使TDD系统的优势无法发挥。

The device treated by the process is of small loss of drain radio-frequency current and increased electric breakdown strength of device as well as delivered power.
