SIM7600SA_User Manual_V1.00 2017-10-11
 Receiver Type: 16-channel, C/A Code
 GPS L1 Frequency: 1575.42±1.023MHz
 GLONASS: 1597.5~1605.8 MHz
 Update rate: Default 1 Hz
 GNSS data format: NMEA-0183
 GNSS Current consumption : 100mA (GSM/CDMA 1X/UMTS/LTE Sleep ,in total on VBAT
pins)
 GNSS antenna: Passive/Active antenna
Note: If the antenna is active type, the power should be given by main board because there is no
power supply on the GPS antenna pad. If the antenna is passive, it is suggested that the external
LNA should be used.
4.3.2 GNSS Application Guide
Users can adopt an active antenna or a passive antenna to SIM7600SA. If using a passive antenna,
an external LNA is a must to get better performance. The following figures are the reference
circuits.
