6 Electrical Characteristics
Notes:
1. Device should operate in the frequency range allocated by regional regulatory authorities. Target operating frequency
range is configurable by software.
2. For the modules that use IPEX antennas, the output impedance is 50 Ω. For other modules without IPEX antennas,
users do not need to concern about the output impedance.
3. Target TX power is configurable based on device or certification requirements.
