CONFIGURABLE SINGLE AND DUAL VCOS FOR DUAL- AND TRI-BAND WIRELESS COMMUNICATION SYSTEMS |
摘要 |
A wireless communication with a receiver subsystem capable of supporting communications operating on two or three distinct frequency bands while incorporating only one or two oscillating devices, respectively. For example, such a subsystem could be integrated in a wireless communication hand-held device configured to operate within three frequency ranges in order to support Cellular, PCS, and GPS services. The receiver subsystem includes a receiver subsystem front end configured to receive first, second, and third receive signals operating under three different frequency bands.
