5 RF Specifications
Appropriate antenna type and design should be used with matched antenna parameters according to
specific application. It is required to conduct a comprehensive functional test for the RF design before
mass production of terminal products. The entire content of this chapter is provided for illustration only.
Analysis, evaluation and determination are still necessary when designing target products.
5.1. Wi-Fi & Bluetooth
The module provides a shared antenna interface: ANT_RF for Wi-Fi and Bluetooth functions. The
impedance shall be kept as 50 Ω. You can connect external antennas such as PCB antenna, sucker
antenna or ceramic antenna to the module via these interfaces to achieve Wi-Fi and Bluetooth functions.
