The invention discloses a pulse super-broadband receiver which comprises a controllable gain amplifier and a triggering receiver in mutual connection, wherein the controllable gain amplifier amplifies a received RF signal and outputs the RF signal to the triggering receiver, and the triggering receiver judges whether the energy of the amplified RF signal excesses the preset value, if the energy of the amplified RF signal excesses the preset value, asynchronous triggering is carried out to obtain high electric level, or else, low electric level is obtained. The pulse super-broadband receiver uses a simple digital logic circuit for receiving the super-broadband pulse, avoids the limitations of high power consumption, complex circuits, difficult integration, and the like of the traditional synchronous sampling receiving method in receiving super-broadband signals, has the advantages of simple circuits, easy integration and low power consumption, and is particularly suitable for the super-broadband pulse communication. The invention can correctly receive the signal and greatly reduce the power consumption and the complexity of the receiving circuit, and is helpful for chip realization.
