A BAW based Transceiver used as Wake-Up Receiver

This work presents a BAW based transceiver which can be used as a wake up receiver. The low power consumption can be achieved by using a high duty cycle. In contrast to typical quartz based systems, the BAW based approach allows for a high repetition rate of the duty cycle, which is not possible with conventional systems. The sensitivity of the receiver is -90 dBm at a current consumption of 8 mA in active mode.
