Abstract

The invention discloses a transmission detection device for a radio frequency terminal and a control method thereof. The device comprises a radio frequency feedback receiver and a calibration controller. The output end of the radio frequency feedback receiver is connected with the calibration controller. The radio frequency feedback receiver comprises a test signal generator, a gating switch and apreprocessing circuit. The input end of the preprocessing circuit is selectively connected with the test signal generator or a detection point of a radio frequency terminal through the gating switch.The preprocessing circuit is used for preprocessing an input signal. The output end of the preprocessing circuit is taken as the output end of the feedback receiver. The calibration controller comprises a digital signal processor. The digital signal processor is used for controlling the gating switch of the feedback receiver and calibrating the radio frequency feedback receiver or the radio frequency terminal according to an output signal of the radio frequency feedback receiver. The accuracy of the device and the control method are relatively high.
