RF Calculator Pro

RF Calculator Pro is a utility application consisting of various calculations, conversions and reference tables. Radiation: • Electromagnetic wave (wavelength, frequency, period) • Propagation delay (distance vs. time) • Resonance (frequency, inductance, capacitance) • Radiated power (vs. VSWR) • Air core inductors (inductance, turns) RF Link: • Free space path loss (loss, distance) • Link budget (RSSI, fade margin) • Fresnel zone (1st, max, 60%, Er) RF Base Station: • Transmission line (Tx, Att, Pout) • EIRP ERP (effective radiated power) • Antenna down-tilt – angle (angle, distance) • Antenna down-tilt – coverage (inner & outer radius) Radar: • Power density (W/m²) • Maximum range (distance) Losses: • Attenuators (Pi, Tee) • VSWR (voltage standing wave ratio) • Reflection coefficient (Rho) • Return loss (dB) • Mismatch loss (dB) Converters: • Power (dBm, Watt, dBW) • Voltage (V, dBV, dBµV) • Current (dBµA, dBA, A, µA) • Terminated (dBm, dBµV, dBµA, V) • Field strength (dBµV/m, V/m, dBmW/m², dBµA/m, W/m², dBpT) • Distance (cm, m, in., yd, km, mi.) Reference: • RF spectrum (ITU) • Amateur bands • Amateur band plan – IARU region 1 • Amateur Q codes • Phonetic alphabet (NATO) • Decibel suffixes • SI unit prefixes • Abbreviations
