PMI and AmpliTech Introduce Low Noise Amplifier System

May 24, 2010

PMI and Amplitech introduced 1:1 redundant low noise amplifier systems that are designed to offer continuous operation without disruption of signal transmission.

If a fault with the main LNA occurs, the unit will automatically switch to the standby LNA to avoid a disruption of signal transmission. The unit can be manually switched as well.

The redundant LNA system consists of an outdoor amplifier/switch assembly that can be mounted to the antenna hub and a rack mounted indoor control module.

Features include: lowest noise temperatures available; fully redundant; hot swappable power supplies; remote control via - RS422, RS485 and Ethernet; automatic/manual control modes; remote status; amplifier current fault detection; weather resistant LNA/switch assembly; Tim-Stamped Alarm History; front panel LNA bias control and monitoring.
