5. Antenna interface
SIM5320A provides RF antenna interface. Customer’s antenna should be located in the host board and
connected to module’s antenna pad through micro-strip line or other types of RF trace and the trace impedance
must be controlled in 50Ω.The maximum gain of the GSM antenna gain should not exceed 3dBi considering the
SAR radio. No antenna gain may be used that would exceed the 2W EIRP power limit in 1900MHz band.
SIMCom recommends that the total insertion loss between the antenna pad and antenna should meet the
