Need to know the power transmission

Hello Team,

We are working on a product based on apq8016 and using wcn3660b chipset for wifi.

We want to measure the power transmitted through the RF circuit using pin PDET_IN (schematic attached). Please do let us know how can we measure this using software (Linaro-18.01 platform).

Also, let us know how to convert the measured voltage on PDET_IN into the power.

Regards,
