Ku band LNA 1:1 redoundancy system
The redundancy system is applicable to company's all LNA. The whole system consists of a low-noise amplifier platform (3 LNA, 1 working +1 redundancy) and an outdoor controller. This product is applicable to remote areas and unattended satellite communication stations.
■ extremely low system noise temperature
■ LNA current real-time monitoring and current abnormal alarm
■ low power consumption and high cost performance
■ easy to install and maintain
