Smith Designer is a powerful and interactive Smith Chart tool for RF and Microwave professionals, students, and hobbyists. Design, analyze, and optimize impedance matching networks directly on your mobile device. This is a feature limited version, a full featured version is also available. The Smith Designer Lite version allows up to 3 elements per network and up to 2 networks per project. Whether you are designing an antenna match, an amplifier interstage, or a filter, Smith Designer provides an intuitive interface to visualize impedance transformations in real-time. Key Features: • Interactive Smith Chart: Visualize impedance trajectories as you add components. Toggle between Impedance (Z) and Admittance (Y) grids. • Schematic Editor: Build matching networks using a drag-and-drop interface. Supports Series/Shunt Inductors, Capacitors, Resistors, series and parallel RLC, Transmission Lines (Series and shunt, Open/Short Stubs), Transformers, fixed jX and jB, and S2P blocks. • Real-Time Tuning: Adjust component values using sliders or by dragging points directly on the Smith Chart to see immediate effects. • Auto Match: Automatically synthesize L-network matching circuits to match a source to a load. • Simultaneous Conjugate Matching for unconditionally stable devices, and provisions to help stabilize conditionally stable networks. • Optimization: Built-in gradient descent optimizer to fine-tune component values for the best match. • Frequency Sweeps: Analyze your design over bandwidth. Plot S-Parameters (S11, S21, S12, S22), Gain (Ga, Gp, Gt), Noise Figure, Return Loss, and Group Delay. • Monte Carlo Analysis: Simulate manufacturing tolerances. Define component variations (Uniform, Gaussian, Triangular) and visualize the spread on the Smith Chart to ensure design robustness. • S2P/Touchstone Support including noise data: Import .s2p files for S-parameter blocks and .s1p files for frequency-dependent source/load impedances. • Vendor Libraries: Easily import and use component libraries (supports Murata LPB format, see https://www.murata.com/tool/data/librarydata). • Comprehensive Overlays: Visualize VSWR circles, Constant Q arcs, Stability circles, and Noise circles (requires noise parameters). • Load Pull Contours: Import multi-frequency Load Pull and MDIF files. Frequency interpolation (nearest, linear, cubic spline). Filled contours with 5 color maps. Reference/contour plane transforms through the matching network. • Data Explorer to assess SnP data files, load-pull data files, antenna patterns and more. Advanced Tools: • Analytical Line Models: Closed-form Z₀, loss, and synthesis for Coaxial, Parallel Lines, Twisted Pair, Microstrip, Stripline, Grounded CPW, Rectangular Waveguide, and Circular Waveguide. • Transmission Line Models: Constant Phase, Electrical Length, and Physical models with loss and velocity factor. • Resonator & Attenuator Designers: Built-in calculators for common circuit blocks. Export & Share: • Export professional PDF reports with schematics, charts, and plots. • Export designs as SPICE netlists for further simulation. • Save high-resolution PNG/SVG images. • Share project files to collaborate with others. Perfect for RF engineering coursework, ham radio antenna tuning, and professional circuit design. Unlock the power of the Smith Chart in your pocket!
