Abstract
A wireless device configured for simultaneous voice and data communications is described. The wireless device includes a voice and data transceiver. The voice and data transceiver includes data path circuitry, voice path circuitry, a first multiplexer and a second multiplexer. The first multiplexer sends a primary data receive signal to the data path circuitry and receives a data transmit signal from the data path circuitry. The second multiplexer sends a diversity data receive signal to the data path circuitry, sends a voice receive signal to the voice path circuitry and receives a voice transmit signal from the voice path circuitry. The wireless device also includes a first antenna coupled to the first multiplexer. The wireless device further includes a second antenna coupled to the second multiplexer.
