Product List1 x Quectel RM520N-GL 5G ModuleOther ContentBefore installation, check the host board, SIM circuit, antenna plan, thermal environment, and carrier certification needs. The module is intended for compatible M.2 Key B platforms; antennas and host system are not included in the package.The official overview shows the four antenna connectors, ANT0, ANT1, ANT2, and ANT3, on the RM520N-GL 5G module.The module uses standard MHF4/IPEX4 RF connectors for external Sub-6 and GNSS antennas.When inserting a coaxial cable plug, keep the connector vertical to avoid damaging the RF receptacle.When removing the coaxial cable plug, keep the angle at 90 degrees so the antenna connector is protected mechanically.ResourcesOfficial Quectel RM520N Series 5G Module datasheetFAQIs the RM520N-GL a global 5G module?Yes.
