5. Electrical Characteristics

1. Device should operate in the frequency range allocated by regional regulatory authorities. Target operating frequency

range is configurable by software.

2. The typical value of ESP32’s Wi-Fi radio output impedance is different between chips in different QFN packages. For

ESP32 chips with a QFN 6×6 package, the value is 30+j10 Ω. For ESP32 chips with a QFN 5×5 package, the value is

35+j10 Ω.

3. Target TX power is configurable based on device or certification requirements.
