Product Number: ADF4159
If I intend to design an FMCW radar using ADF5901 and ADF4159, and I only want to use the AUX and RFINA in single-ended mode for connection, is this feasible? In this case, should the corresponding complementary AUX be left floating, and RFINB be grounded through a capacitor? Additionally, the datasheet of ADF5901 indicates that its AUX single-ended output is typically -5 dBm. However, for ADF4159, the minimum input of RFIN is -10 dBm, and it is not specified whether this is for single-ended input. Therefore, I would like to confirm whether the -10 dBm here refers to the minimum value for single-ended input; if so, the single-ended output of -5 dBm would meet the requirement.
