The nrf52833‘s RF power accuracy at selecting the emission power of +8dBm

I'm sorry, but we do not have a graph for this, as this is related to the antenna design on nRF5x series devices. We have a description that should shed some more light on this in our RF Performance Test Guidelines whitepaper here. Sections 5.1 Modulation bandwidth theory & 6.1.2 Sensitivity accuracy here should be helpful.

Best regards,

Simon

Hello Simonr,

Thanks your prompt response.

If possible, could you share the Gaussian distribution graph on the power accuracy of nRF52833, because we would like to understand its power accuracy performance for the link budget calcuration in the complex radio propagation environment?

BR,

Kiyoshi

In theory, the output power could deviate by +- 4dBm, but the distribution of output power is highly Gaussian (normalized), with most SoCs always being much closer to the set value. Under normal conditions you'll most likely see +- 2dBm deviation at worst.
