Abstract
Certain aspects of a digital baseband transmitter with digital RF/IF support in GSM/GPRS/EDGE compliant devices may comprise receiving digitized data within a chip. A control signal may be generated within the chip indicating whether the received digitized data is to be processed by an IF processing interface or a digital RF processing interface. The baseband processor has the capability to work together with different kinds of RF chips on the market and since this design is implemented on a single module, most of the circuits are shared which reduces the die size significantly. This design also provides a customer more flexibility to choose among different RF vendors.
Claims36
A method for supporting GSM, GPRS and EDGE utilizing a baseband transmitter, the method comprising:
- receiving digitized data within a chip;
- and
- generating at least one control signal from within said chip, which indicates whether said received digitized data is to be processed by an IF processing interface or a digital RF processing interface.
A machine-readable storage having stored thereon, a computer program having at least one code section for supporting GSM, GPRS and EDGE utilizing a baseband transmitter, the at least one code section being executable by a machine for causing the machine to perform steps comprising:
- receiving digitized data within a chip;
- and
- generating at least one control signal from within said chip, which indicates whether said received digitized data is to be processed by an IF processing interface or a digital RF processing interface.
A system for supporting GSM, GPRS and EDGE utilizing a baseband transmitter, the system comprising:
- circuitry for receiving digitized data within a chip;
- and
- circuitry for generating at least one control signal from within said chip, which indicates whether said received digitized data is to be processed by an IF processing interface or a digital RF processing interface.
