D.Antenna
The EFR32MG13 family includes devices which support
both single-band and dual-band RF communication
over separate physical RF
interfaces.
The 2.4 GHz antenna interface consists of two pins
(2G4RF_IOP and 2G4RF_ION) that interface directly to
the on-chip BALUN. The
2G4RF_ION pin should be grounded externally.
The sub-GHz antenna interface consists of a differential
transmit interface (pins SUBGRF_OP and
SUBGRF_ON) and a differential re-
ceive interface (pinsSUBGRF_IP and SUBGRF_IN).
The external components and power supply
connections for the antenna interface typical
applications are shown in the RF Matching
Networks section.
