As radio frequency (RF) applications occupy larger bandwidths, nonlinear dynamics
become nonnegligible. This work presents a theoretical framework capable of quantifying …

The paper presents a conceptual discussion of the characterisation and phenomenology of
passive intermodulation (PIM) by the localised and distributed nonlinearities in passive …

This paper presents a quantitative metric for memory effects in power amplifiers (PAs) and
applies it to various active device technologies and wireless system contexts. The proposed …

This paper presents a methodology to compute the distortion output of a class of third-order
nonlinear dynamic systems from only standard two-tone test results. Closed-form …

A large signal vector intermodulation network analyzer with a dynamic range of 90 dB and
phase resolution of better than 2/spl deg/is reported. The analyzer is used in conjunction …

In this paper, the design of a general feed-forward topology for modeling RF power
amplifiers (PAs) is presented. It consists of producing the best nonlinear nonrecursive …

Modeling and characterization strategies were developed to capture the complex nonlinear
behavior of both the components within an RF circuit and within an assembled system …

Mobile and Satellite applications are progressively moving towards broader bandwidths, so
nonlinear long-term memory effects manifested by RF Transmitters must not be neglected …

Baseband effects result in asymmetrical distortion of RF communication signals through the
interaction of baseband-related distortion with in-channel distortion. Here, a behavioral …

This paper presents a procedure to design a non-recursive model, suited for simulation and
able to model short-and long-term memory effects, that is the best nonlinear approximator …
