This paper explains why an external low noise amplifier results in a better performance. Next generation mobile handsets will be equipped with GSM, WLAN, Bluetooth and GPS. Integrating all these functionality onto one printed circuit board gives housing problems or cohabitation challenges. Some of them can be solved easily at low cost but others cannot. In this paper the GPS and its cohabitation with GSM and WCDMA will be explained.
