    摘要： A communication terminal (10) and a method for initiating a communication link from a communication terminal to a remote party, where the method includes sensing input of an address number for the remote party. Upon sensing the input of an address number a plurality of selectable items (152-157), representing different communication channels usable for setting up a communication link from the terminal, are presented on a display (15) of the terminal. A navigation tool (141) can be used to change selected communication channel, such as from voice call (152) to messaging (153), after which setting up of a communication link using the selected communication channel can proceed.

    摘要： An envelope tracking power supply arranged to generate a modulated supply voltage in dependence on a reference signal, comprising a first path for tracking low frequency variations in the reference signal and a second path for tracking high frequency variations in the reference signal, and further comprising a combiner having a low frequency combining element for the first path and a high frequency combining element for the second path, and for generating the modulated supply voltage, wherein there is further provided sensing circuitry for sensing a resonance signal in the low or high frequency combining element, and adjusting circuitry for adjusting a signal in the first path in dependence on the sensed resonance signal.
