Abstract
An apparatus comprising a signal generator for generating a polar representation of a signal. The apparatus comprises further a first filtering unit configured to filter a low frequency part of the amplitude component of said signal and a second filtering unit configured to filter a high frequency-part of the amplitude component of said signal. In addition, the apparatus includes a pulse width modulating unit configured to modulate the filtered high frequency part of the amplitude component of said signal together with the phase component of said signal. Finally the apparatus includes a DC-DC converter configured to convert the filtered low frequency part of the amplitude component of said signal. Said DC-DC converter supplies a switching mode power amplifier for amplifying the pulse width modulated signal.
