Abstract :
This work presents the first monolithic integrated circuit that provides precise, scaled measurements of gain and phase difference between two signals up to 3 GHz. A 60 dB gain range and 180 degree phase range are achieved with 30 mV/dB and 10 mV/degree scaling, respectively. This function has wide application for in-situ measurement of vector RF parameters and in linearization of transmission systems such as power amplifiers.
