Abstract

A polar modulator arrangement has a first and a second node to receive a digital signal with a first and a second component corresponding to a digital amplitude component and a digital phase component. A digital interpolation filter generates an interpolated first component by interpolating and filtering the first component. A polar modulated radio frequency signal is generated by a combination element as a function of the interpolated first component and the second component.
