90nm 2.4GHz wake up receiver
The wakeup receiver offers a superior low cost wireless solution for applications with stringent battery life time requirement. The receiver operates at 2400MHz ISM band. It supports the main radio to carry out ultra-low power channel monitoring, and wake up the main radio only when a valid trigger packet is detected.
Different from other wakeup receiver designs, which needs a pair transmitter to send the data that fulfills a certain packet structure, this wakeup receiver can pair with any transmitter operating at 2400MHz, as long as the signal is with a constant envelope. As we know, the popular standards, Bluetooth Low Energy (BLE) and Zigbee, both adopt the modulation scheme with a constant envelope. This also means that this wakeup receiver can work directly with existing systems to provide a very low power channel monitoring.
The receiver SoC integrates analog front end (AFE) , digital baseband (DBB), and clock generation system, which makes the receiver a complete solution ready for use.
