4.3.2 Conducted Transmit Power

The conducted transmit power is another indicator that measures the performance of EM820W. The conducted transmit power means the maximum power that the module tested at the antenna port can transmit. According to the 3GPP protocol, the required transmit power varies with the power class.

Table 4-3 lists the required ranges of the conducted transmit power of EM820W. The tested values listed in the Test Value column must be within the range from the minimum power to the maximum power.
