20W B8 FDD-LTE RF Power Amplifier with LNA
ZDTECH’s data acquisition electronic fence RF power amplifier module is designed to meet modern wireless communication requirements. It features 6 functional ports for power supply, communication and control. Equipped with SMA-50KFD and MCX connectors, it enables reliable RF link construction. The module supports configurable PA and LNA monitoring parameters with a baud rate of 9600. For thermal protection, the PA shuts down at +85°C and restarts at +65°C. It also provides over-power alarm, standard-compliant reverse power detection and high-precision temperature monitoring, ensuring stable and safe operation of communication systems.
