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