(nRF52832)Tx power level under extreme operation conditions

[Mitsuhiro]

Hi,

When evaluated under the following conditions, there was a temperature dependence (See the following Results ). 

1. How mach temperature dependence of TX power?
2. Does TX power level increase as the temperature decreases?

Conditions

　DUT: nRF52 DK

    TX power Setting: +4dBm

    Power supply: 3.0 V

    temperature: -40, 25, +85℃

Results

    TX power level:

        around +5dBm(-40℃)

        +4dBm(25℃)

        around +3dBm(85℃)

Most radio parameters will vary over temperature. When it comes to output power and sensitivity, you can expect around +/- 1 dB over temperature, where output power and sensitivity is highest at the lowest temperature. 

The numbers you see here are normal.
