I am integrating the evaluation board of the ADF5355 synthesizer into an existing RF system. In the RF system my power supplies availability is limited to 5V and 12V, the ADF5355-eval board however prefers a 6V supply. Looking for a matching solution here:
After inspecting the eval board circuit layout, see attached screenshot, with its on board regulators (ADM7150), I think that the 12V supply could work. The regulators can handle the 12V. The only component I can see that does not agree is the the Zener Diode (ZD1), which would have to be replaced. This would be an easy fix. Or am I missing some power supply requirements?
