ZED-F9T-Integration manual
Figure 32: Minimal ZED-F9T design
For a minimal design with the ZED-F9T GNSS modules, the following functions and pins should be
considered:
• Connect the power supply to VCC and V_BCKP.
• If hot or warm start operations are needed, connect a backup battery to V_BCKP.
• If USB is not used connect V_USB to ground.
• Ensure an optimal ground connection to all ground pins of the ZED-F9T GNSS module.
• If antenna bias is required, see ZED-F9T antenna bias section.
4.4 Antenna
The ZED-F9T requires an active antenna with integral LNA to ensure good performance under
nominal signal reception.
When implementing a custom antenna installation, it is recommended that an OEM active antenna
module be used that meets our specification. Implementing a custom active antenna design is an
important exercise to meet the required bandwidths and group delay specifications compared to
previous L1-only designs.
