    ... DC voltage on the common mode feedback pin CMFB. Since the input signal is AC-coupled the RF output voltage will swing (symmetrically) around this DC level. 14 RGADJ The coupling of the TZA1024 to the signal processor (SAA7324) can be either AC or DC. When an AC-coupling is chosen (see Fig.8) the minimum supply voltage can be ...
