e-peas - Model AEM30940 -RF Energy Harvesting IC Solution
E-peas’ RF energy harvesting IC solution – AEM30940 – is an integrated energy management subsystem that extracts DC power from ambient RF signal to simultaneously store energy in a rechargeable element and supply the radio frequency energy harvester with two independent regulated voltages. This allows product designers and engineers to extend battery lifetime and ultimately get rid of the disposable battery in a large range of wireless recharge, industrial monitoring, home automation, etc.
