RF Calculator

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
