Proposal on Layout of Product in Terminal Product
In the layout of notebooks, it is necessary to ensure ZM8620 is not placed close to the switch
power supply, and high-speed signal line, and protection well the layout of these interference
sources. At the same time, do not place the antenna and connection network card and antenna
coaxial cable close to these interference sources. It is necessary to ensure not to place ZM8620
close to components such as CPU, hard disc, and South Bridge so as to ensure heat
dissipation.

Diversity Antenna Design
ZM8620 supports diversity receiving function, and if it is necessary to support diversity, the
notebook needs to add diversity antenna. The design method of the diversity antenna is
consistent with the main antenna, and its efficiency index is allowed to reduce by 3 dB. The
