Energy harvesting ic rf. This allows product designers and engineers to extend battery lifetime and ultimately get rid of the disposable battery in a. E peas aem40940 rf energy harvesting ic is an integrated ambient energy manager aem that can extract ac power from a high frequency 868mhz 915mhz or 2 45ghz rf input simultaneously storing energy in a rechargeable element and supplying the system with two independent regulated voltages. E peas rf energy harvesting ic solution aem40940 is an integrated energy management subsystem integrating a rectifier that extracts ac power from ambient rf waves to simultaneously store energy in a rechargeable element and supply the system with two independent regulated voltages. The general layout of an rf energy harvesting system consists of a receiving antenna with a suitable design a rectifier and a dc dc circuit.

Where p i are the powers in transmission and reception the latter being the most interesting to evaluate the energy harvesting power supply g i are the gains of the two antennas λ the rf wavelength and r the distance between the two antennas. The ic can manage poorly regulated sources such as energy harvesting devices with output levels ranging from 1µw to 100mw. 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. 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 system with two independent regulated voltages.

Power management products that convert energy from vibration piezoelectric photovoltaic solar and thermal tec teg thermopiles thermocouples sources provide high efficiency conversion to regulated voltages or to charge batteries and super capacit. For rf energy harvesting it has two ics one for extracting ac power from ambient rf signals the other for extracting dc power. There the energy can be stored in a capacitor connected to vcap or fed to the boost converter pcc210. The boost converter defaults to 3 3v output but can be adjusted by adding resistors to vset.

Rf energy is fed into the device where it reaches the rf to dc converter ic pcc110. The aem40940 is designed to to extend battery. E peas aem40940 rf energy harvesting ic is an integrated ambient energy manager aem that can extract ac power from a high frequency 868mhz 915mhz or 2 45ghz rf input simultaneously storing energy in a rechargeable element and supplying the system with two independent regulated voltages.
