Hi I' using an ADF6720 Eval board whith a AD-FMCDAQ2-EBZ board.
I've connected I and Q signals directly between the AD9144 DAC's outputs and the ADF6720 Inputs, because both circuits are with the same polarisation voltage 0.5V.
I and Q signals are delivered by the DAC, and applied to the ADF6720baseband Inputs but RF outpout remains off.
The only signaI that can see is the LO at a very low level -70dBm.
Is there any register to set On/Off the RF output ?
When I start the boards, the base band inputs remain at 0 volts until the DAC is activated, do you think this could destroy modulators ?
What is the max allowable voltage range on Base band input ?
Thanks for your support
