fspl — Calculate free-space path loss (FSPL) in decibels using the ITU-R P.
link_budget — Compute a full RF link budget from transmitter power, frequency, distance, and antenna gains.
dipole — Calculate physical dimensions of a dipole antenna for a given frequency.
microstrip — Calculate PCB microstrip trace width for a target characteristic impedance using the Hammerstad-Jensen closed-form equations.
dbm_convert — Convert a power level in dBm to milliwatts, watts, dBW, and RMS voltage across a given impedance.
noise_figure_cascade — Calculate the cascaded noise figure of a multi-stage receiver chain using the Friis formula.
vswr — Convert between VSWR, return loss, and reflection coefficient — provide any one parameter and get all related impedance-mismatch metrics.
attenuator_pi — Design a Pi-topology resistive attenuator pad.
