SEMCAD X TCAD of Mobile Phones: Heading for a Generic Modeling Approach ? Schmid Partner Engineering AG SEMCAD X SEMCAD X TCAD of Mobile Phones: Heading for a Generic Modeling Approach April, 2007 SEMCAD X TCAD of Mobile Phones: Heading for a Generic Modeling Approach ? Schmid Partner Engineering AG Motivation: ? still fast growth in MTE sector (3G/4G, WLAN, BlueTooth, pervasive computing, etc.) ? high quality, low pricing and short product cycles required ? increase in public concern in the possible adverse effects of RF exposure (especially concerning MTE), mandatory safety guidelines introduced ? increasing interest for EM TCAD tools supporting RF engineers ? new hardware acceleration platforms hugely reduce simulation times for complex structures SEMCAD X TCAD of Mobile Phones: Heading for a Generic Modeling Approach ? Schmid Partner Engineering AG Typical Simulation Processes: ? numerical device verification: + modeling: import, simplification/modification, excitation, etc. + simulation: freespace analysis + validation: measurement of impedance, near- and far-field - numerical model is accurate: CAD, materials parameters, gridding/discretization, power normalization, etc. ? against-the-head compliance: validation of peak spatial ave. SAR ? OTA performance: influence of environment ( e.g. wholebody, hand, car) on RF performance in terms of detuning, efficiency, TRP, etc. ? antenna integration: complete optimization device performance for all significant RF and SAR parameters ? failure synthesis: quality control through extensive evaluation of e.g. manufacturing tolerences on overall device performance SEMCAD X TCAD of Mobile Phones: Heading for a Generic Modeling Approach ?
