ResoSynth
WAVEGUIDE FILTER SYNTHESIS

Engineering depth without the repetitive setup.

ResoSynth combines filter-specific synthesis, physical response analysis, machining-aware geometry, tolerance insight, thermal tools, and export-ready 3D models in one focused desktop workflow.

CORE CAPABILITIES

From specification to verification-ready geometry.

Different waveguide topologies need different physics. ResoSynth uses specialized synthesis and reduced-order electromagnetic methods rather than forcing every filter through one generic model.

DESIGN SPEED

Near-instant synthesis & rapid optimization

Move from electrical requirements to a calculated design in seconds, making it practical to evaluate alternatives quickly before committing time to full 3D EM setup and verification.

  • Near-instant calculations
  • Rapid optimization
  • Reduces hours of design time to seconds
  • Shortens design cycles
MANUFACTURABILITY

Fillet-aware synthesis

Supported synthesis workflows include machining fillet effects so the physical design can move closer to practical hardware instead of assuming ideal sharp corners everywhere.

  • Machining radius as a design input
  • Physical geometry tied to synthesis
  • Practical dimensions for downstream CAD
RF RESPONSE

S-parameters & group delay

Review synthesized S11/S21 behavior, absolute group delay, and group-delay ripple directly alongside the design dimensions.

  • S11 / S21 response plots
  • Absolute group delay
  • Group-delay ripple and markers
THERMAL

Thermal drift & CW power

Estimate response movement with temperature and evaluate steady-state CW thermal power using material loss, thermal resistance, temperature limits, and safety margin.

  • Temperature-dependent response shift
  • CW thermal power estimate
  • Material-aware conductor-loss estimates
PRODUCTION INSIGHT

Tolerance & yield analysis

Move beyond a nominal design. Explore manufacturing variation with tolerance analysis and Monte Carlo-style yield estimation before committing to hardware.

  • Dimension-tolerance variation
  • Monte Carlo yield assessment
  • Production-oriented risk visibility
3D EXPORT

HFSS & STEP export

Carry the synthesized design into downstream verification with export-ready 3D internal RF geometry for HFSS and STEP-based engineering workflows.

  • Parametric HFSS Python builders
  • 3D STEP geometry export
  • Dimensions preserved from the synthesized design
DESIGN DATA

Geometry & dimension tables

Keep electrical and mechanical decisions connected with calculated geometry tables, physical dimensions, body length, material selections, and estimated insertion loss.

  • Calculated section dimensions
  • Material and loss estimates
  • Clear engineering summaries
ENGINEERING CONTROL

Solver and workflow controls

Tune analysis accuracy, sweep density, plot axes, geometry constraints, and topology-specific settings without rebuilding an EM project from scratch.

  • Accuracy and sweep controls
  • Topology-specific constraints
  • Fast design iteration
FOUR SPECIALIZED MODULES

Different topology. Purpose-built solver path.

ResoSynth is organized around real waveguide filter classes, with synthesis and analysis choices matched to each physical structure.

ANALYZE BEFORE YOU EXPORT

More than a dimension calculator.

A synthesized geometry is only the beginning. ResoSynth keeps response, delay, material, thermal behavior, and tolerance yield connected to the same design so engineering tradeoffs can be reviewed before full 3D EM verification and hardware.
