Advertisement
An RF to DC energy harvester converts ambient radio frequency energy into usable direct current power for low power electronic devices. These systems support battery free operation in wireless sensors, IoT devices, smart tags, wearable electronics, and remote monitoring applications where conventional power sources are limited. The popular manufacturers of RF to DC converter IC modules include Powercast Corporation, E-Peas, RF DIAGNOSICS etc.
RF to DC Converter Introduction
The chip device or module which converts RF energy to DC (Direct Current) energy is known as an RF to DC energy harvester. They provide harvested energy to the storage elements attached. The typical applications include capacitor and battery recharging, battery less wireless sensors, low power consumer electronics, sensors, displays and microprocessors etc.
The RF to DC conversion reference designs are developed specific to different standards viz. NFC, UHF, WiFi, Bluetooth, 4G and various frequency ranges (13.56 MHz, 915 MHz, 2.45 GHz, 1710-1915 MHz).
The figure depicts the position of the RF to DC converter module in an RF energy harvesting system. As shown, it is placed between the RF antenna and the charge management module. The charging module can either be a capacitor which stores charge or a rechargeable battery.
