13.56mhz (nfc) wireless charger modules-ag凯发旗舰厅

rohm's 13.56mhz wireless charger module is designed for small sensor and wearable devices. it realizes wireless charging of ultra-small devices, which is difficult with the qi standard. since 13.56mhz is the same frequency band as the nfc communication standard, it is possible to share the antenna for power supply and nfc communication. by using the power transmission and the power reception modules that have been adjusted for antenna design and matching as a pair, the development man-hours for antenna design and matching adjustment can be significantly reduced.
