Abstract: A wireless terminal is provided that includes a first receiver that includes a first input unit configured to perform impedance matching on a first reception signal to output a first RF input signal. A first amplification unit is configured to amplify the first RF input signal to output one or more first RF output signals in an inter-band CA mode and an intra-band CA mode. A first output unit is configured to down-convert at least one of the one or more first RF output signals to a baseband. A second receiver includes a second output unit. In the intra-band CA mode, the one or more first RF output signals includes a first RF signal and a second RF signal, and the first amplification unit is further configured to provide the first output unit with the first RF signal and provide the second output unit with the second RF signal.

Abstract: A method and a supply modulator (SM) are provided for supplying power from a wireless transmitter to a radio frequency (RF) power amplifier. A power control signal input from a modem is received. A reference voltage is determined. An operating mode of the SM is changed by controlling a level of the reference voltage. A voltage is determined based on the level of a reference voltage. When the operating mode of the SM is an ET mode, a first output signal from a linear regulator and a second output signal from a switching regulator are combined to obtain a combined result, and the combined result is output. The first output signal is based on the voltage. When the operating mode of the SM is an APT mode, the voltage based on the reference voltage is output.
