Dear Support Engineer,
In AD9361 Reference Manual, it states that "The LNA input pins have DC bias (~ 0.6 Vdc) present on them and may need to be ac-coupled depending on the common-mode voltage level of the external circuit". First of all, I can not find a pin named Vdc on the data sheet, so what is the Vdc value on AD-FMCOMMS3-EBZ eval board? I use a signal generator to send a 300MHz single frequency to the AD9361 receiver - does the signal from the generator needs to be AC biased like (-2dBm to +2dBm), or should it be (0 to +4dBm)?
Thank you for your time,
