In order to simplify my layout, I would like to use the ADFR670X IQ modulator with the integrated PLL for MIMO application. The setup is as below. The ADRFs would be on different boards.
For this chip, I havent seen a phase resync option like in ADF4351. Does it mean that we cannot align 2 ADRF's outputs and I have to go back with an external LO?
Thanks for the support.
