RF and Electronics Calculators

1. Wavelength ↔ Frequency Converter

Frequency (Hz): Calculate Wavelength (λ = v / f, with v = 3×10⁸ m/s) Wavelength (m): Calculate Frequency (f = v / λ)

2. Resonant Frequency (LC Circuit)

Inductance (H): Capacitance (F): Calculate f₀ = 1 / (2π√(LC))

3. Capacitive Reactance

Capacitance (F): Frequency (Hz): Calculate X_C = 1 / (2πfC)

4. Inductive Reactance

Inductance (H): Frequency (Hz): Calculate X_L = 2πfL

5. Transmission Line Characteristic Impedance (Z₀)

Inductance per unit length (H/m): Capacitance per unit length (F/m): Calculate Z₀ = √(L / C)

6. Standing Wave Ratio (SWR) and Return Loss

Load Impedance (Ω): Characteristic Impedance (Ω): Calculate SWR = (1 + |Γ|) / (1 - |Γ|)
