Abstract
A transceiver circuit and a method in a wireless communication network are provided, where a signal power level for a signal received at the transceiver circuit is measured and compared to a predefined threshold power level. At least two groups of power amplifiers may be used, where one group is optimized for high efficiency above the predefined threshold power level, and one group is optimized for high efficiency below the predefined threshold power level. The amplifiers may be used to amplify the received signal depending on the signal power level in relation to the predefined power threshold level. The signal may then be filtered by duplex filters and forwarded to a diversity antenna or a main antenna where it is transmitted over an air interface.

14. A device comprising:
a processor to; determine a signal power for one or more signals to be transmitted, direct the one or more signals, when the determined signal power is above a particular power threshold, to one or more first amplifiers with an efficiency above the particular power threshold and not to one or more second amplifiers with an efficiency below the particular power threshold, and direct the one or more signals, when the determined signal power is below the particular power threshold, to the one or more second amplifiers and not to the one or more first amplifiers. - View Dependent Claims (15, 16, 17, 18, 19, 20)
