3.4.1 GPS RECEIVER
The GPS receiver input employs a single-ended connection realized by this pin. The GPS input is
routed from the GPS antenna switch, through a band-pass filter and then an impedance transformer
circuit that optimally matches the impedance looking into the GPS LNA. The impedance transformer
circuit topology is shown in Figure 1-7.
