Radiated Field
VSWR & Reflection
Amplitude & Power Converter
—dBm
Theory: Converts between logarithmic and linear units in a 50Ω system.
Formula: dBµV = dBm + 107 | P = V²/R
Formula: dBµV = dBm + 107 | P = V²/R
Field Strength & Required Power
—Field Strength (V/m)
Theory: Calculates the electric field intensity ($E$).
Formula: E = √ (30 * P * G_linear) / d
Formula: E = √ (30 * P * G_linear) / d
TEM / GTEM Cell Field
—Field Strength (V/m)
Theory: Field strength inside a TEM cell depends on the septum distance.
Formula: E = √ (P * Z_cell) / h (Where $Z=50Ω$)
Formula: E = √ (P * Z_cell) / h (Where $Z=50Ω$)
VSWR & Reflection Analysis
OR
0.200

Formulas:
Γ = (VSWR-1)/(VSWR+1)
Return Loss = -20log(Γ)
Mismatch Loss = -10log(1 – Γ²)
Γ = (VSWR-1)/(VSWR+1)
Return Loss = -20log(Γ)
Mismatch Loss = -10log(1 – Γ²)
* All calculations assume a characteristic impedance of 50Ω.
