Very interesting and detailled power consumption figures.
Thanks a lot for this.

Hi Jean-Samuel.
Pdet1&2 dedicated for Output power detectors and Vcnt1&2 for test points
voltage control.
For example, PA +24V and feeder supply voltage 28..36V of DC-DC converter
(in case of positive type, i.e. minus connected to chassis).
Each input of ADS1015 contains divider of 1:10, so it makes possible to
measure up to 41V with 0.01V resolution.
Best regards,
Andrey Sviyazov.

Hi Andrey,
I can see in the UmSEL 4 channels ADC.
What do you plan to do with this ?
What is Pdet and Vcnt ?
I ask you this because it would be really nice to use 2 of these ADC
channels to monitor each of the 2 PA RF Pout.
What would you think about this ?
Best regards.
Jean-Samuel.
