Harmonic Load-pull Simulator
The Web-based Harmonic Load-pull Simulator (HeLPS) is a next-generation RF/microwave design tool that dramatically reduces design time and lowers costs to improve circuit performance. HeLPS utilizes the company’s proprietary large-signal modeling technology and standard SPICE models to allow designers to perform first-round optimization of circuits without prototyping or testing in hardware. The software solution uses a standard Internet browser and Java Apple-based graphical user interface to determine optimum circuit design parameters.

Microwave Studio Software
The CST MicroWave Studio (MWS) (version 2) is a state-of-the-art software tool designed specifically for the calculation of high frequency fields on a Windows-based PC. The software incorporates the Perfect Boundary Approximation™, an extension of the Finite Integration technique, for precision and performance; a modeller that enables the fast definition of complex structures; a three-dimensional Eigenmode solver; and built-in power macro language, which allows thorough integration of MWS into Windows. Typical applications of MWS include the simulation of waveguides, couplers, power splitters, filters, planar structures, connectors and antennas.
