Abstract :
This work presents a theoretical discussion on the ability of traditional noise power ratio (NPR) setups to characterize the in-band signal distortion of general RF circuits. It is shown that NPR tests are optimistic in estimating co-channel distortion, as they are blind for the signal-correlated components. Therefore, an alternative standard for co-channel distortion specification and the associated measurement setups are theoretically proposed and experimentally validated
