Electrical – RF & Signal Integrity
Winchester Electronics engineers use highly advanced, best-in-class software tools, equipment, and technologies during the design, development, and verification/validation phases of their projects. Parts are first designed in a 3D CAD environment and then simulated to obtain an optimum electrical performance given a specific set of parameters and requirements, based on the application. Finally, the simulation results are correlated and validated to actual measurements, reducing repeated design iterations and redundant prototypes.
Simulation
Whether your application is RF or digital driven, the bottom line is that you will need some kind of modeling and simulation analysis. Our simulation capabilities encompass multiple domains and types of analysis in order to provide a comprehensive, integrated design solution. Our engineers will build, model and analyze models that illustrate the RF and Signal Integrity effects of your application, and provide a final solution that meets your design requirements.
