Abstract
A method for power measurement includes applying a nonlinear function to a Radio Frequency (RF) signal that includes a modulated component and a spurious component, so as to produce a broadband signal that includes a Direct-Current (DC) component, a baseband component and one or more High-Frequency (HF) components. The broadband signal is Band-Pass (BP) filtered so as to produce a bandpass signal from which the DC and HF components are removed. Based on the bandpass signal, a power of the modulated component in the RF signal is estimated irrespective of the spurious component.
