• Insertion loss (1565.42–1585.42 MHz) = 2.0 dB (Max)
• Insertion loss (1597.5515–1605.886 MHz) = 2.0 dB (Max)
It is recommended to add a DC block to the customer’s GPS
application to prevent damage to the ME910X1-mPCIe module due to
unwanted DC voltage.
Combined GNSS Antenna
The use of a combined RF/GNSS antenna is NOT recommended. This solution can
generate an extremely poor GNSS reception. Furthermore, the combination of antennas
requires an additional diplexer, which adds significant power loss in the RF path.
Linear and Patch GNSS Antenna
Using this type of antenna introduces at least 3 dB of loss compared to a circularly
polarized (CP) antenna. Having a spherical gain response instead of a hemispherical gain
response can aggravate the multipath behavior and create poor position accuracy.
Please refer to the Module’s Hardware User Guide for detailed
information about GPS operating modes and RF signal requirements.
