About this app

Aether is a comprehensive RF and Microwave engineering toolkit for professionals, students, and enthusiasts. From system-level link budget analysis to component-level PCB design, Aether covers the full RF design workflow in one app.

An Aether Lite version is also available.

System Budget Calculator:
• Cascade Analysis: Chain amplifiers, mixers, filters, propagation channels, and attenuators to compute system Noise Figure, Gain, IP3, and P1dB at every stage.
• Link Budget: Calculate received power, SNR, and link margin for wireless systems.
• Sensitivity & Dynamic Range: Compute receiver sensitivity and spurious-free dynamic range.
• Export professional cascade reports as PDF, SVG and draw.io.

Filter Designer:
• Filter Synthesis: Butterworth, Chebyshev I & II, Elliptic, Bessel, Gaussian, and Legendre-Papoulis responses.
• Filter Classes: Low Pass, High Pass, Band Pass, and Band Stop.
• Implementation: Passive LC ladder and Transmission Line realizations.
• Frequency and component value scaling with tolerance analysis.
• Full S-parameter simulation with magnitude, phase/delay, pole-zero, and schematic views.
• Export reports and datafiles.

IQ Simulator:
• Signal Generator: Create CW, two-tone, and Gaussian noise signals, or load IQ data files.
• Spectrum, IQ waveforms, constellations and CCDF plots.
• Export IQ data as CF32, HDF5, or other industry-standard files.

Smith Chart Designer:
• Interactive Smith Chart with drag-and-drop schematic editor.
• L, C, R, Transmission Lines, Transformers, and S2P blocks.
• Amplifier Design: Gain, Stability, and Noise Circles for LNA and PA design.
• Auto Match, optimization, Monte Carlo analysis, and Load Pull contours.

• 3D antenna radiation pattern viewer with polar cuts.
• Marker system, trace math, and snapshot comparison.

Trace Designer (BEM Solver):
• Full 2D Boundary Element Method solver for PCB transmission-line cross-sections.
• 9 structures: Microstrip, GCPWG, Stripline, Differential, Coated, and Embedded variants.
• Multilayer substrates, trapezoidal conductor profiles, roughness models, and E-field visualization.
• Impedance synthesis and manufacturing tolerance analysis.

Analytical & Transmission Line Tools:
• Closed-form models for 8 line types with Z₀ synthesis and loss computation.
• Resonator and Attenuator Designers.

Export & Share:
• PDF reports, PNG/SVG screenshots, draw.io diagrams, Touchstone files.

The complete toolkit for RF system design, circuit analysis, and PCB engineering.
