Patent ID: 7062249

Claim:
A method for processing signals in a mobile terminal, comprising: receiving an RF signal; and controlling a switch, based on a band-selecting signal from a controller, to route the RF signal to one of a plurality of signal processing stages, each of said signal processing stages processing signals in a respective one of a plurality of frequency bands, the routing further comprising: routing the RF signal to a DCN duplexer if the RF signal is in a frequency band which includes DCN signals and then to one of said signal processing stages processing signals in a DCN frequency band; routing the RF signal to a GPS band pass filter if the RE signal is in a frequency band which includes GPS signals and then to one of said signal processing stages processing signals in a GPS frequency band; and routing the RE signal to a PCS duplexer if the RF signal is in a frequency band which includes PCS signals and then to one of said signal processing stages processing signals in a PCS frequency band, and wherein the switch provides isolation between bands producing optimal receiver sensitivity to be maintained at respective bands since other bands do not interrupt.
