FluxSim’s Browser-Based RF Lab

Field notes

The workspace combines schematic capture with RF and microwave libraries, SPICE compact models, digital logic, and planar Method-of-Moments layouts. Its examples range from a 1 MHz synchronous buck and CMOS inverter chain to a 28 GHz phased array and a 50 GHz coupled microstrip line. JSON design files and Touchstone .s2p files provide explicit project and measurement interchange points. The page labels the product v1.0-beta, so the visible breadth should not be read as evidence of validated engineering accuracy.
