Power Density & Field Level (Far Field)
Use this tool to calculate the radiated field strength (in V/m) based on amplifier power, antenna gain, and distance.
Formula: E = √(30 × P × G) / d
Where:
- E = Field strength (V/m)
- P = Power (W)
- G = Gain (from dBi)
- d = Distance (m)
This tool assists in:
Field strength compliance: Verifying that your setup complies with immunity standards for electromagnetic compatibility (EMC).
Optimizing RF test setups: Identifying the appropriate power amplifier and antenna combinations to meet specific testing requirements.
Safety and EMI evaluation: Assessing potential radiation hazards or electromagnetic interference (EMI) risks in different environments.
