Part Number: BQ501210
i am using the BQ50120EVM as Transmitter and BQ51050EVM 764 as Receiver.
1) What is the tuning method for using different Tx with the BQ50120EVM
Currently there is a 247nF capacitor (designators C16,C11,C19) and the inductor = 10uH.
it is not fit the operational frequency of 125kHz.
so what is the exact formula for tuning?
2) how can I increase the operational distance ?
I can give each up efficiency and i can give up compliance with the Qi standard In other words what can be done in the EVM HW wise in order to work in larger distance (currently even 12-13 mm is not an option) even in the cost of working at 10-20% efficiency and without compliance to the Qi standard.
3) what it the minimal coupling coefficient (k) that the system is working with.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
