Abstract
Wireless mobile terminals include a GPS Radio Frequency (RF) receiver and a wide bandwidth radiotelephone RF receiver having bandwidth that is at least half as wide as the GPS RF signal chip frequency. The wireless mobile terminals also include a shared Intermediate Frequency (IF) section that is responsive to both the GPS RF receiver and to the wide bandwidth radiotelephone RF receiver. A demodulator such as a CDMA despreader is responsive to the shared IF section. Thus, common circuitry may be provided except for the separate GPS RF receiver and wide bandwidth radiotelephone RF receiver. Low cost manufacturing and high efficiency operations may thereby be provided.
