3.4 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 1-6.
