(NFrx, see Appendix B)
8.5 dB with 15 dB net pre-amplification
18 dB with 25 dB net pre-amplification
26 dB with 35 dB net pre-amplification
35 dB with 45 dB net pre-amplification
RF nominal input impedance
50 Ohms

1
The net gain is the total pre-amplification of the distribution network in front of the module. Typically, this
equals antenna active LNA gain minus coax losses in the applicable GNSS bands.

The listed noise figure is at room temperature. Add 1 dB for the noise figure at the worst temperature corner
(85°C)
