AEM30940 RF Energy Harvesting IC e-peas AEM30940 RF Energy Harvesting IC is an integrated Ambient Energy Manager (AEM) that can extract DC power from a piezo generator, a microturbine generator, or any other high-frequency 868MHz or 915MHz RF input, simultaneously storing energy in a rechargeable element and supplying the system with two independent regulated voltages. The AEM30940 extends battery lifetime and eliminates the primary energy storage element in many wireless applications, such as industrial monitoring, home automation, transportation, and smart agriculture.
