ADRV9026 ACLR Typical Performance

Hello,

I have a question regarding the ADRV9026 TX ACLR performance. The data sheet quotes numbers for 20MHz LTE waveform at -12dBFs.

1) Is the -12dBFs the complex I+Q back-off setpoint?

2) What is the waveform envelope PAPR?

3) The ACLR numbers range from -65dBc to -68dBc. Are these numbers achieved with DPD or wo DPD?

Regards

Ibrahim
