4 Antenna interface
The RF interface has an impedance of 50Ω. To suit the physical design of individual applications
SIM5215A offers two alternatives:
z Recommended approach: antenna connector on the component side of the PCB
z Antenna pad and grounding plane placed on the bottom side.
To minimize the loss on the RF cable, it needs to be very careful to choose RF cable. We
recommend that the insertion loss should meet the following requirements:
z GSM900/GSM850 <1 dB
z DCS1800/PCS1900 <1.5 dB
z WCDMA 1900 <1.5 dB
z WCDMA 850 <1 dB
4.1 Antenna installation
4.1.1 Antenna connector
SIM5215A use MURATA MM9329-2700 RF connector on the module side, we recommend that
user uses MURATA MXTK88XXXXX as matching connector on the application side. Please
refer to appendix for detailed information about MURATA MXTK88XXXXX.
