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.
