3.4 GPS RECEIVER
The GPS(GNSS) path has its own antenna and receiver front-end circuit. In some applications, only a bandpass
filter and matching network is needed. This filter is similar to the filters used at the DRx inputs – a single-ended
input and differential output. The GPS(GNSS) input port has a differential configuration with a 100
