Equal Ripple Filter Optimization
We offer unique filter optimization engines that work in conjunction with many popular RF/microwave design tools and with some EM simulation tools. Our optimizers consistently find an exact equal ripple response in the filter passband. We can optimize single bandpass filters, diplexers and multiplexers. Unlike general purpose optimizers, our software realizes the exact bandwidth that you specify and it finds all the reflections zeros in the passband defined by the filter order. This is all made possible by decades of research and practical filter design experience.

Equal Ripple Optimization
for NI/AWR Microwave Office

Equal Ripple Optimization for NI/AWR Microwave Office (EQR_OPT_MWO) is a designed to supplement the optimizers provided in Microwave Office. It can optimize any filter that can be defined in the NI/AWR design environment with full access to the element catalog. It will optimize single bandpass filters, diplexers and multiplexers to an exact equal ripple response. It can also be used to port tune S-parameter files imported from any EM simulator.

Equal Ripple Optimization
for Mician uWave Wizard

Equal Ripple Optimization for Mician uWave Wizard (EQR_OPT_MWW) supplements the optimizer provided in uWave Wizard. It will optimize single bandpass filters, diplexers and multiplexers to an exact equal ripple response. For filters that can be desribed with only mode matching models the optimization is quite fast. It is possible to include some 2D or 3D FEM models in the filter optimization as well.

Equal Ripple Optimization
for Keysight Genesys

The V2.0 release of Equal Ripple Optimization for Keysight Genesys (EQR_OPT_GENESYS) supplements the optimizers provided in Genesys. It can optimize any filter that can be defined in the Genesys design environment with full access to the element catalog. The V2.0 release will optimize single bandpass filters, diplexers and multiplexers to an exact equal ripple response. It can also be used to port tune S-parameter files imported from any EM simulator.
