Wake-up system with passive correlator

An object of the present invention is to provide a wake-up system applied to the wireless transceiver, such as a remote controller, a mobile phone. Wake-up system of the present invention is received by the transmitter, the wake-up signal and the wake-up signal and to each Coral illustration encodes the delayed signal by a delay time, and transmits the encoded signals, a receiver, a reception from the transmitter, decoding the signal with the received signal illustration Coral delayed signal by a delay time, respectively, is made so as to convert the decoded signal into a direct current switching voltage (VSW) provided in the power switching signal for the wake-up. According to the present invention, and to run on the SAW matched filter passive components identical to Coral illustration of Coral concentrator to a transmitter and a receiver comprising such ,, by implementing conversion to a wake-up signal into a signal necessary for the receiver to wake-up, It can reduce the power consumption of the wake-up. Wireless transceiver, a remote control, emulator manually Coral, wake-up system, the SAW matched filter
