(VCC=3.3V, VCC_PA=5V, RF output power 27dBm) while the module is sending data, how can I supply it?
The power supply circuit must be able to deliver the peak current, either from the DC/DC converter, of by using a super-cap to help buffer the charge. It is important to check that the supply voltage does not drop during the transmission.
