7.3 RF performance measurement 

Table 7-2 below shows the RF performance in conductive test. Please note that, there is no external 

PA refer to Semtech’s reference design, so the RF power is output from SX125x FEM directly. The 

maximum output power normally would be 6-7dBm type in different band.
