Receiver noise figure
10 dB (with 15-dB net gain)
The receiver noise figure increases as the net gain increases,
but its contribution to the system noise figure decreases.
The worse case is for a net gain of 15dB.
RF nominal input impedance
50 Ohms
VSWR
< 2.5:1 in 1200-1251 MHz and 1560-1610 MHz range

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