I need to build cylindrical coil for RX receiver of a wireless charging system and define the TX receiver coil with main chip controller in TX and RX section.
It is not important for me the electric schematic of this project because I can made myself but I need to define commercial chip to do this application
For the TX there are not problems because I have 15x8cm of surface size.
The problem is for RX receiver because I need to use a diy cylindrical coil.
Maximum dimensions for this coil are 22mm of diameter and 45mm of lenght with 5W of power.
This coil has to be in air.
