The Solution Note

1. The solution uses GDT in the front end of the transformer to do common mode (eight lines) surge protection.

2.The back end of the network transformer uses TVs with small volume and low junction capacitance to absorb differential mode energy. The TVS has fast reaction time and takes into account the function of electrostatic protection.

3. Comply with 802.11 electrical standards.

4. Meet IEC61000-4-5, GBT17626.5 and other surge test standards.

5. Meet IEC61000-4-2, GBT17626.2 and other electrostatic test standards.
