Hi, i am trying to measure the matching impedance of the antenna. I have the following questions:What is the driver stage and how can i turn if off?How can i ensure that register 0x28 is set to 0x0F?How can i ensure that tr_am bit is set to 1?Thank ...

What is the maximum power that i can use? Which pin can i use to feed the board with external power? What is the max power that is transmitted to the RF circuit of the board? Which are the limitations in power?
