RF Calculator Pro

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
