• Non-Linear X-Parameters
• Provide mathematically correct extensions of S-parameters to large-signal conditions with fully nonlinear framework that provides both the magnitude and phase of the distortion.
• Cover both large-signal and small-signal conditions, and capture complete linear and nonlinear behavior at all loads.
• Characterize the amplitudes and relative phase of harmonics generated by components under large input power levels at all ports.
• Correctly characterize impedance mismatches and frequency mixing behavior to allow accurate simulation of cascaded nonlinear xparameter blocks, such as amplifiers and mixers in wireless design.
• Apply to individual transistor modeling as an alternative to, supplement to, or validation of traditional compact equivalent circuit modeling.
• Can be measured using a non-linear vector network analyzer, such as a suitably optioned Keysight PNA-X series instrument.
• Can be measured as a function of impedance and bias.
• Can be simulated in multiple circuit simulation tools, such as Keysight ADS and Keysight Genesys software.
