ADRV9026 Typical ACLR Performanc

Ibrahim_VT said:

1) Is the -12dBFs the DAC I+Q setpoint, i.e. is it -15dBFs per I and per Q?

-12dBFS is DAC I+Q setpoint

2) The ACLR is reported as -65dBc to -68dBc. Is that achieved with or without DPD? Also do these numbers include the contribution of Phase noise?

It is without DPD as it is small signal level. Yes, including the contribution of phase noise.

Thanks Ramarao for the quick and concise answers. I have  follow up questions if that's ok:

1) So just to confirm the DAC -12dBFs setpoint is for the envelope and in that case is the transceiver using one of your DACs with 10mA FS per phase?

2) What is the envelope (I+Q) PAPR of the LTE waveform that was used to report the -65dBc ACLR?

Yes, the DAC -12dBFS setpoint is for the envelop and how are you saying that the transceiver using one of the DACs with 10mA FS per phase, are you referring to any document?

It should be 9.7dB at 0.01% probability for the LTE 20MHz signal.

Thanks Ramarao.

I based my comment on the Aux DAC description "The auxiliary DACs are 12-bit converters capable of supplying up to 10 mA."
