7 Radio integration
The module antenna connection has a characteristic impedance of 50 Ohms.
In order to get the best sensitivity and output power, it is recommended to implement a matching circuit between
the module and the antenna:
In order to design the matching circuit :
- test with direct connection in the first step
- adjust inductors and capacitors in a second step if needed
