Connector mode: U6100 uses MURATA’s MM9329-2700RA1 RF connector on the rear side, it is recommend to use
MURATA’s MXTK92XXXXX as matching connector. Please refer to MURATA’s MXTK92XXXXX documents for
more information.
Solder pad mode: The antenna can also be soldered to the pad on the module which has a ground pad close to the
antenna pad.
The RF connector is shown in Figure 2-6.
