Application information
Table 12.
1. In case Zs=Zl, ZA and ZB can be replaced by two resistors of same value: RA=RB=|Zs|.
2. Defining ZTTX as the impedance of RTTX in series with CTTX, RTTX and CTTX can also be calculated from the following
3. In this case CTTX is just operating as a DC decoupling capacitor (fp=100 Hz).
