AD9361 PA usage

Question asked by DWW_Wolf on Jan 12, 2015

Hi,

 

the AD9361 contains 2 baseband branches for the TX TX1 and TX2. Each TX has 2 PA (TX1A, TX1B; TX2A, TX2B), reference data sheet.

 

Questions are:

How can we setup to use both PAs for one TX branch i.e. TX2A and TX2B and/or TX1A and TX1B at the same time?

 

Is there between TX2 and TX1 a delay of one sample due to the shrinked digital interface or is it synchronized internally?

 

We use our own plattform where the PAs TX1A/B and TX2A/B are connected.

 

Kind regards,

 

Andreas
