About this app

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
