Hi Team,

FB3 isn't shown in Figure 40 shown below. I would like to know where can I find the FB3. Thanks!

Best,

Nancy

    Hello,
    The FB3 ferrite bead is optional. Please keep in mind the figure only shows a typical PoC network for 4G and other implementations are possible provided the system return loss and noise requirements are met. You can refer to Table 223 for the PCB board return loss requirements.
