RF Calculator Pro(圖1)-速報App

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:
