Protection device resistant to high-power electromagnetic pulse damage and signal receiver

The invention provides an anti-high-power electromagnetic pulse damage protection device and a signal receiver, and the device comprises an impedance matching module which is connected with an input port so as to receive an input signal inputted by the input port, and carries out the impedance matching of the input signal, and obtains a first signal; the signal filtering module is connected with the impedance matching module to receive the first signal and filter the first signal to obtain a second signal; the first signal reflection module is connected with the signal filtering module to receive the second signal and perform reflection processing on the second signal to obtain a third signal; and the signal amplification module is connected with the signal reflection module so as to receive the fourth signal, amplify the fourth signal and output the amplified signal through an output port. Transmission of emission signals in input signals is facilitated, interference signals, especially high-power electromag
