I got a new EVB ADRF6720-27 and spent two days to get it work and going nowhere so far. There is no RF signal coming out of RF_OUT port. I have baseband inputs, Ref_IN, LO out and all the power supply checked, they are all fine. The enbl is also enabled. I am out of ideas now.
it would be really appreciate it if any help can provide? The attached is the register settings.
