摘要

Cellular handsels play the roles of MP3 player, TV, radio, navigator, camera. Web browser. PDA and. yes, telephone. Feature creep provides opportunities for the system designer, but semiconductor integration takes them away at the same time. The hottest new feature in handsets is GPS to enable navigation features and location-based services. Implementation options for GPS vary. One option is to add a GPS receiver to an existing design. Receivers such as the uN3010 from Atheros and PMP2525 Hammerhead II from Infineon integrate easily into mobile designs. Coming in BGA or CSP packages and integrat- ing digital and RF functions, the receivers connect to a host processor using a serial port and to an antenna via an external SAW filter.
