Compared with the Basic Device Modeler, the Advanced Device Modeler provides even more comprehensive models, taking complex phenomena into account. It enables parametric models to be extracted for circuits whose performance may vary as a function of digital controls (such as variable gain amplifiers, programmable phase shifters and beamformers). See Multi-Function Chip (MFC) behavioral modeling for accurate beamforming simulations Whitepaper.

The most complete power amplifier model is also available in this module. This incorporates all the phenomena that can occur in a circuit as described herafter.

Finally, the antenna modeler can be used to use far-field simulation data supplied by a third-party EM simulator, to extract an equivalent model of the antenna, so that the antenna impedance can be used directly to simulate the realistic behavior of the power amplifier when the two circuits are assembled.

The Advanced Device Modeler Add-On allows more advanced behavioral models extraction for different circuit types:


Bilateral (B) nonlinear model of power amplifiers with high-frequency (HF) memory effects linked to the carrier frequency and low-frequency (LF) memory effects linked to the modulation frequency of the envelope with electrical and thermal phenomena.

The HPA-B-HF-LF model family can be used to generate other HPA models depending on the input Data available to extract the model: HPA-U-HF, HPA-B-HF, HPA-B-HF-T°, HPA-U-HF-LF. 



Linear models of multifunction circuits, integrating commands defining the attenuation and phase parameters of the component characterized by multi-state S-parameters (citi-file format)



An SnP block representing the antenna model to consider the mutual coupling between different unitary radiating elements of the array.

This modeling tool allows importing into VISION the S-parameter files and far-field data provided by EM simulation. HFSS (an Ansys’ EM simulator) or CST ( A Dassault Systèmes’ EM simulator) are supported.

VISION can calculate the incident and reflected signal at each port of the antenna array, allowing accurate calculation of the active impedance and radiation.
