RF Simulation Tools
Server-side computation for tasks too heavy for in-browser calculators.
Broadband Impedance Matching Synthesizer
Synthesize L, Pi, T, or ladder matching networks for broadband impedance transformation. Enter source/load impedances across a frequency band and get optimized component values with simulated S-parameters.
RF Filter Monte Carlo Analysis
Analyse how component tolerances affect your filter's passband ripple and stopband rejection. Run thousands of Monte Carlo trials to get yield and worst-case statistics.
Eye Diagram from S-Parameters
Upload a Touchstone (.s2p) file and generate a PRBS-15 eye diagram. Extracts insertion loss, group delay, and impedance profile, then renders the eye with jitter and ISI.
NEC2 Wire Antenna Simulation
Simulate wire antennas (dipoles, yagis, loops) using the NEC2 method-of-moments engine. Get 3D radiation patterns, gain, impedance, and efficiency across a frequency sweep.
S-Parameter Analysis Pipeline
Upload up to 4 Touchstone files and get insertion loss, return loss, group delay, TDR impedance profile, and passband ripple — all in one automated report.
FDTD Transmission Line Simulator
Full-wave 3D FDTD simulation of microstrip stubs, coupled-line filters, via transitions, and step discontinuities using openEMS. Get S-parameters, Smith chart, and impedance analysis.
SMPS Control Loop Stability Analyzer
Model switch-mode power supply control loops using small-signal transfer functions. Get Bode plots of T(s), extract phase margin, gain margin, and crossover frequency, then run Monte Carlo trials over component tolerances (L ±20%, C ±20%, ESR ±50%, load ±30%) to compute manufacturing yield.
EMI Radiated Emissions Estimator
Estimate radiated emissions from PCB loops and cables using Paul's analytical DM/CM models. Monte Carlo confidence intervals vs. FCC Part 15 and CISPR 32 limits.
Magnetics & Transformer Design Optimizer
Vendor-agnostic NSGA-II optimizer finds Pareto-optimal core and winding designs across 113 cores (EE, ETD, PQ, RM, Toroid) from TDK, Ferroxcube, Magnetics Inc., and Micrometals. Minimizes total loss and volume simultaneously — shows the full efficiency-vs-size trade-off frontier.
Radar Detection Performance Monte Carlo
Compute probability of detection (Pd) vs range for pulsed radar systems. Select Swerling target model (0–IV), specify antenna gains, noise figure, pulse parameters, and rain rate. Monte Carlo over RCS fluctuations and system uncertainties produces Pd confidence bands and ROC curves.
PDN Impedance Analyzer & Decoupling Capacitor Optimizer
Optimize decoupling capacitor selection for PCB power delivery networks. Model plane-pair cavity resonances, specify board geometry and target impedance, then let the genetic algorithm find the optimal capacitor combination to keep Z_PDN below your target across all frequencies.
Satellite & Terrestrial Link Budget
Compute probabilistic link margins using ITU-R propagation models (P.618 rain, P.676 gaseous, P.840 cloud). Enter EIRP, G/T, frequency, and site location. Get a full line-by-line budget, availability curve, and Monte Carlo confidence intervals over rain, pointing, and EIRP/G·T uncertainties.
RF Cascade Budget Analyzer
Compute cascaded noise figure, gain, IIP3, and P1dB for an N-stage RF signal chain using Friis formulas. Paste your stage list as JSON, set your system specs, and get a line-by-line cascade table, sensitivity analysis, and Monte Carlo yield statistics across component tolerances.
