Hi,

I am working on the OFDM transmitter system. I have observed that the carrier signal peak power level is -3dBm whereas the peak power level of the OFDM (256 sub carriers) signal observed is -42dBm. Also the channel power measured is -42dBm . Frequency of operation is 2.45GHz. Power amplifier used is MMZ25332BT1.

I would like to know if this is a expected phenomenon (Power of modulated signal is lower than the continuous wave power).

PS - Measured power levels are attenuated power levels (20dB external attenuator).
