Hello, i have a question regarding Eval board AD8302. the input voltages are 274 mV and the signal is modulated by 10Mhz. the phase difference between two signal is 0 so i was expecting an output voltage in VPHS pin around 1.8 V but it was 2.34 V ( Vpos 3.7 V). the value was same even if i didnt put any inputs and was changing according to Vpos. I tried with different input voltage ranging -60dBm to 0 dBm and also with phase differences. But it seems like its not working. im really confused and need help.
