RF-Design N+1 redundant L-Band Amplifier Chassis

The HQR445C is a compact and modular N+1 redundant L-Band line amplifier system built into a 1RU/19” rackmount chassis. The variable gain adjustment ranges from 0 – 40dB (1dB steps) while it also supports slope equalization so to achieve best performance within the RF distribution chain. The HQR445C chassis holds up to five high dynamic HQA45MI amplifier modules (950 – 2150MHz or 850 – 2700MHz) thus allowing an amplifier redundancy operation from 1+1 to max. 4+1 (field expandable, hot swappable).The redundancy switching between any of the active and the hot-standby amplifier modules is done by a high performance RF switch with a very short switchover time thus a stable signal transmission at any time is assured. The unit also features RF power monitoring, threshold alarming and comes with 1:1 redundant dual power supply (hot swappable). The front panel OLED display and keypads allows easy local monitoring and configuration. Remote configuration and monitoring is possible via its rear side Ethernet-Interface (WebGUI, SNMP). All active components of the unit such as amplifier modules, power supplies, ventilators, CPU and the OLED display are permanently monitored and hot swappable for ease of expansion and/or replacement This flexible, modular and expandable 4+1 line amplifier is perfectly suited for RF distribution infrastructures in Teleports, Satellite Earth Stations, as well as Broadcast- and Broadband facilities wherever accurate RF power, highest stability and availability is necessary.
