RF and microwave network-parameter utilities for GNU Octave. Provides S-parameter conversions (ST, SZ, SY, SABCD, SH, SG), cascading, de-embedding, port reordering, renormalization, mixed-mode conversion for differential pairs, and Touchstone I/O. Function signatures match the MATLAB RF Toolbox, so the same user code runs in both environments. Cross-validated against MATLAB R2025b, MATLAB R2020b (backwards-compatibility), and scikit-rf 1.11.0 to floating-point precision — 144/144 pair-wise tests pass across all four comparison pairs.
