WP7702: LTE RF Transmission Path Test

Dear all,

As part of evaluating the LTE performance of our WP7702 module, I am currently using the “AT!” commands provided in the datasheet. However, when increasing the transmission power to 23 dBm, I observe harmonics whose peak level exceeds -20 dBm.

My question is whether these harmonics will also be present in real-life operating conditions or if they only appear during testing. More specifically, I would like to determine if the AT! commands disable some on-module filtering that affects the signal integrity and leads to the generation of harmonics.
