Application GPS Receiver

As GPS devices become mobile phone or other handheld device integration solution part, their tolerance for interference of adjacent cells will be the key. For example, a dual-band CDMA cell phone GPS work can be carried out. At this point, the power amplifier on the typical CDMA transmit power is 25dBm. Assuming crosstalk canceller and GPS passband filter topology to isolate the -70dB frequency band signal, GPS receivers will face -45dBm with outer interference levels.
