APPLICATIONS & SOLUTIONS / ENERGY HARVESTING APPLICATIONS

RF

Would our RF (Radio Frequency) Energy Harvesting Solutions be right for you?

Let’s assume that you work with battery powered IoT wireless devices that operate within wireless waves rich environments. Without energy harvesting, you need to replace the batteries of those devices, because they run out of energy. This generates operational costs.

But there might be enough of energy provided by the wireless emitters surrounding your devices that you could use to power them.
Those emitters include:

GSM900 (BTx)925-960 MHz
GSM1800 (BTx)1805-1880 MHz
3G (BTx)2110-2170 MHz
WiFi2400-2500 MHz

And if not, you can equip the environment with dedicated emitters emitting power at 868MHz (Europe) or 915MHz (USA).

When properly selected and sized (frequency compatibility with available sources), an antenna and a balun (provided by e-peas for all above mentioned frequency ranges) combined with our state of the art energy harvesting PMICs will recharge the batteries of your IoT applications from ambient RF power.

Using e-peas’ RF energy harvesting, you will avoid typical operating costs associated with battery replacement.

What exactly does e-peas offer?

Best performing solutions that make your devices’ batteries live forever. Our innovative ICs autonomously and efficiently recharge your batteries from received RF power levels as low as -19dBm.

e-peas offers you 2 AEM [Ambient Energy Manager] references:

  • The AEM30940 allows you for harvesting energy from -18dBm up to 10dBm using properly selected external antenna, balun and rectifier
  • The AEM40940 integrates an RF rectifier and allows you for harvesting energy from -19dBM up to 5dBm using a properly selected external antenna and balun.

Why e-peas? How does e-peas differ from competitors?

This reference is based on e-peas unique AEM platform offering:

  • top energy conversion efficiency
  • the fastest supercapacitor charge
  • the lowest cold-start power
  • the smallest footprint and associated components BOM

In addition, you will get direct access to engineering support by our designers.
