Antenna Interface
The antenna connection is one of the most important aspect in the whole application
design as it strongly affects the overall radio performance. Hence, please read and follow
the requirements and the guidelines as carefully as possible.
FN990 Family modules provide four MHF-4 type RF connectors covering the 5G
FR1/LTE/WCDMA bands including GNSS and one MHF-4 type RF connector dedicated to
GNSS.
Warning: When connecting cellular and GNSS antennas to the
module, pay special attention not to damage RF connectors.
