A reference design of GNSS antenna interface is shown as below.
Figure 30: Reference Circuit of GNSS Antenna Interface
1. An external LDO can be selected to supply power according to the active antenna requirement.
2. If the module is designed with a passive antenna, then the VDD circuit is not needed.
5.3. Wi-Fi Antenna Interface*
BG95-MF supports Wi-Fi antenna interface through which the module realizes Wi-Fi positioning
(receiving only).
The following tables show the pin definition of Wi-Fi antenna interface.
