title = "A Behavioral Model For Predicting Third-order Intermodulation Asymmetry Under Broadband Signal Excitation",
abstract = "In modern RF receiving systems, the escalating demand for wider bandwidths and complex signal handling necessitates precise characterization of nonlinear effects in RF amplifiers. The widely adopted Volterra series models suffer from excessive parameters and limited physical interpretability. In this paper, we address the challenge of nonlinearity modeling by proposing a novel behavioral model for predicting third-order intermodulation (IM3) based on the mechanism of second-order intermodulation (IM2) feedback. The proposed behavioral model accurately predicts the asymmetry between high/low third-order intermodulation components of a representative amplifier circuit, with an error within ± 3.05 dBm. The proposed model explicitly links asymmetry in high/low IM3 products to IM2 feedback interactions, offering critical physical insights while significantly reducing parameter complexity.",
