I recently acquired 2 AD8302 evaluation boards to be used to create a Vector Network Analyser. The assembly is as shown below.
The "Gain" output was connected to a multimeter and the "INPA" and "INPB" were connected to a signal generator in order to test how the 0-1.8V output is shown depending on varying changes in magnitude. A DC power supply of 5.5V was also connected.
However I did not get the desired results. Vmag readings did not remotely resemble the output shown in figure 5 of the datasheet. The values I did get are shown below, the frequency of "INPA" and "INPB" were both 1900MHz.
Am I doing something wrong? If so, any help would be greatly appreciated.
