AetherRF

Aether is a comprehensive RF and Microwave engineering suite 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. • Vendor component library import (S2P/industry-standard LPB). • Frequency sweep with S-parameter, group delay, and return loss plots. Data Explorer: • Import Touchstone (.sNp), MDIF, and Load Pull files. • Cartesian, Polar, Smith Chart, and Smith Tube 3D visualizations. • 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.
