a GPS receiver;
a semiconductor package containing both the radio receiver and the GPS receiver; and
a die contained in the semiconductor package,
wherein both the radio receiver and the GPS receiver are fabricated in the die, and the FM band broadcast radio receiver comprises a front end having a first mode in which the front end functions for the FM band broadcast radio receiver and a second mode in which the front end functions for the GPS receiver.
2. The apparatus of claim 1 , wherein the first and second modes are time multiplexed.
3. The apparatus of claim 1 , wherein the front end comprises a local oscillator to generate a first local oscillator signal during the first mode and generate a second different oscillator signal during the second mode.
4. A wireless device, comprising:
a semiconductor package comprising an FM band broadcast radio receiver and a GPS receiver; and
a subsystem coupled to the semiconductor package to receive location information from the GPS receiver,
wherein the FM band broadcast radio receiver comprises a front end having a first mode in which the front end functions for the FM band broadcast radio receiver and a second mode in which the front end functions for the GPS receiver,
wherein the semiconductor package comprises a die, and both the radio receiver and the GPS receiver are fabricated in the die.
5. The wireless device of claim 4 , wherein the first and second modes are time multiplexed.
6. The wireless device of claim 4 , wherein the front end comprises a local oscillator to generate a first local oscillator signal during the first mode and generate a second different oscillator signal during the second mode.
7. A method comprising:
providing an FM band broadcast radio receiver;
providing a GPS receiver;
packaging the radio receiver and the GPS receiver in the same semiconductor package; and
fabricating the radio receiver and the GPS receiver in the same die,
wherein the FM band broadcast radio receiver comprises a front end having a first mode in which the front end functions for the FM band broadcast radio receiver and a second mode in which the front end functions for the GPS receiver.
8. The method of claim 7 , wherein the first and second modes are time multiplexed.
9. The method of claim 7 , wherein the front end comprises a local oscillator to generate a first local oscillator signal during the first mode and generate a second different oscillator signal during the second mode.
10. The apparatus of claim 1 , wherein the radio receiver is adapted to receive at least one of a broadcast radio signal or a service broadcast signal that is within the radio band.
11. The wireless device of claim 4 , wherein the subsystem is part of at least one additional semiconductor package.
12. The wireless device of claim 4 , wherein the subsystem comprises a navigation subsystem or a cellular telephone subsystem.
13. The wireless device of claim 4 , wherein the GPS receiver is adapted to receive assistance information from the radio receiver.
14. The wireless device of claim 4 , wherein the radio receiver comprises at least one of an FM broadcast radio receiver and an AM broadcast radio receiver.
15. The method of claim 7 , further comprising:
adapting the radio receiver and the GPS receiver to communicate assistance information.
16. The method of claim 7 , further comprising:
adapting the radio receiver to receive at least one of an FM, AM, weatherband, digital audio broadcast (DAB) and radio data service (RDS) signal.
17. The apparatus of claim 1 , further comprising:
a processor to be shared between the GPS receiver and the FM band broadcast radio receiver.
18. The wireless device of claim 4 , further comprising:
a processor to be shared between the GPS receiver and the FM band broadcast radio receiver.
19. The method of claim 7 , further comprising:
a processor to be shared between the GPS receiver and the FM band broadcast radio receiver.
