A frequency-domain, Volterra series-based behavioral simulation tool for RF systems

In this paper a new behavioral modeling approach for RF systems based is presented, based on a Volterra series input-output map representation. The modeling is done purely in the frequency domain, capturing the typical system level specifications for RF building blocks, independent of the implementation details. A harmonic balance simulation tool has been developed based on those models. The implementation focuses on deterministic effects such as distortion and frequency conversion. The behavioral simulator has been tested for various systems and results are presented.
