Some EV-ADF70301-915AZ questions

Hi Community,

Please help with these questions.

1. Why EV-ADF70301-915AZ has PA1 and PA2 installed? Can they work at the same time?

2. Can EV-ADF70301-915AZ operate PA1/PA2, and LNAIN1/LANIN2 at the same time?

3. Do I need to design 2 sets of ADF7030-1, one for Rx only and one for TX only, if I need a full duplex RF transfers?
