I am trying to build a multichannel RF transmit system. I am using ADL5385 as IQ modulators to vary the amplitude and phase of each channel.
The problem I am having is: whenever the modulator is powered on, it resets the output phase to be either 0 degree or 180 degree. As a result, the phase difference between the multiple channels could be either 0 or 180 degree, randomly.
So is there a way to overcome this and set the phase to 0 degree everytime I power on the device?
