A simple diode-based nonlinear verification device (NVD) design for nonlinear vector network analyzers is presented together with an improved figure of merit (FOM) parameter that is insensitive to impedance match and isolates variation of the device’s nonlinear parameters. The stability over 84 h and load–pull performance of this new design have been evaluated.
