Abstract

The invention provides a signal transmitting and receiving device, an electronic device and equipment. The signal transmitting and receiving device comprises at least one transmitting channel which isused for transmitting a first signal and at least one receiving channel which is used for receiving a second signal, wherein the second signal is an echo signal formed based on the first signal. Thereceiving channel comprises a first frequency mixer, and the first frequency mixer is used for performing down-conversion on the second signal based on the reference signal; when the signal transmitting and receiving device is in a working state, the frequency of the first signal is the same as that of the reference signal; when the signal transmitting and receiving device is in a self-checking state, the frequency of the first signal is different from the frequency of the reference signal. The invention provides a signal transmitting and receiving device, which can reduce the self-checking cost of a transmitting and receiving machine and save the self-checking time.
