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
