HbFree is intended for simulation of radio frequency (RF) and microwave (MW) analog non-autonomous circuits under multi-tone excitations. It was developed for MW mixers and power amplifiers design. Package contains free version of harmonic balance simulator program "HaBala", Spice-to-Habala translator "s2h" and a few utilities. It allows the following components to be used: R,L,C, transmission lines (lossless for now), V and I sources, Diodes and MESFETs.
