App Description
For RF engineer or Ham
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
• SI unit prefixes
• Abbreviations
