SIM7600SA-H_User Manual_V1.00
2017-10-11
Smart Machine Smart Decision
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-H. If using a passive
antenna, an external LNA is a must to get better performance. The following figures are the
reference circuits.
