RF Calculator is a utility application consisting of various calculations, conversions and reference tables. Calculators: • Wavelength • Free space path loss • Attenuators • Link budget • Resonance • VSWR • Reflection coefficient • Return loss • Mismatch loss • Percentage ERP • Transmission line • EIRP/ERP • Fresnel Zone Converters: • Power (dBm, Watt, dBW) • Voltage (V, dBV, dBµV, dBu) • 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: • Frequency bands (ITU) • Amateur bands • Amateur band plan - IARU region 1 • Amateur Q codes • Phonetic alphabet (NATO) • Decibel suffixes • SI unit prefixes
