3.6 GPS MODE
3.6.1 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 1-9.
