摘要： An integrated circuit for achieving power reduction in a transceiver may include a jammer detector that determines an interference level corresponding to a received signal, and a transmit power detector that determines a required transmit power level for a transmitted signal. The integrated circuit may also include at least one of the following: a process monitor that determines process corners of components within the receiver and/or the transmitter, and a temperature monitor that determines a temperature of the receiver and/or the transmitter. The integrated circuit may also include a state machine. The state machine may transition the receiver from a high linearity mode to a low linearity mode if a set of operating conditions is satisfied. Similarly, the state machine may transition the transmitter from a high power mode to a low power mode if a set of operating conditions is satisfied.

摘要： 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.
