|
| Output power
| The BTS3902E supports two carriers. The output power of the antenna connector in the RF module is 2×5 W.
l Supports single output or MIMO
l Single output: the maximum output power for each transmit channel is 5 W
l MIMO: the maximum output power is 5 W+5 W
l Supports configuration of power amplifiers with different power
The maximum output power equals the maximum output power of the power amplifier minus the internal loss. The maximum output power is measured at the antenna connector in the RF module.
