ABSTRACT:
This disclosure is directed toward a wireless device configured to support a plurality of wireless protocols. More specifically, the wireless device includes signal processing components that can be used in more than one communication mode. Accordingly, distinct components conventionally used in a wireless device that supports a plurality of protocols may be eliminated in favor of one or more common components that can be used in the different communication modes. In one example, an analog filter is used to filter baseband signals associated with a first protocol and a second protocol. A digital filter can then be used to perform additional filtering on digital baseband signals associated with the second protocol. By using a common analog filter for analog filtering of baseband signals associated with different protocols, the architecture and design of a wireless device can be simplified.
