1+1 redundant L-Band / ext. L-Band Amplifier (0 to 40dB gain)

The HQR145C2 represents a 1+1 redundant RF line amplifier in a compact 1RU/19″ rack mount operating at L-Band (950 – 2150MHz) or extended L-Band (850 – 2700MHz) frequency. It comes with variable gain control ranging from 0 to 40dB along with slope equalization and various additional functionalities. Additionally it has two independent and 1+1 redundant operating amplifiers together with an internal RF switch.
The HQR145C2´s two high dynamic 1+1 redundant operating amplifier modules (hot standby) each provide variable gain control 0 to 40dB so to achieve best performance within the network. The redundancy switching between the two amplifier modules is done nearly interruption free with a switchover time of <5ms.
The unit features variable gain control (MGC/AGC), slope-equalization, RF power monitoring, threshold alarming, 2 front-panel monitoring ports and 1:1 redundant dual power supply (hot-swappable). Additional features such as switchable LNB-supply and a 10 MHz reference signal port are optionally available.
The HQR145C2 has a front-side LC-Display/keypads for local configuration. Front-side status LED´s indicating amplifier and power supply status. Remote control and configuration can be done via its rear-side Ethernet-Interface (WebGUI, SNMP).
