Abstract
The present invention concerns an amplifying device arranged to receive an input signal having a certain duty cycle. The amplifying device comprise a first switching unit having an input terminal adapted to receive a first half of the input signal, and an output terminal adapted to be connected to a first signal output where a first half of an output signal is provided. The amplifying device comprise a second switching unit having an input terminal adapted to receive a second half of the input signal and an output terminal adapted to be connected to a second signal output where a second half of the output signal is provided. Also, the first switching unit and the second switching units are adapted to receive an input signal, wherein the first half of said input signal has the same duty cycle as the second half of the input signal but shifted in phase. The present invention also concerns a wireless transceiver and a radio transmission device.
