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
