HQR145C

1:1 redundant L-Band Line Amplifier (0 to 40dB gain)

The HQR145C is a 1:1 redundant L-Band line amplifier (950 – 2150MHz) with variable gain adjustment (0 to 40dB), slope equalization and various additional functionalities in a compact 1RU/19″ design. This line amplifier is perfectly suited for RF distribution infrastructures wherever accurate RF power, highest stability and availability is necessary. The HQR145C is equipped with two high dynamic 1:1 redundant operating amplifier modules (hot-standby) each providing variable gain so to achieve best performance within the network. The redundancy switching between the two amplifier modules is done nearly interruption free. The unit features variable gain control, slope-equalization, RF power monitoring and 1:1 redundant dual power supply (hot-swappable). Additional features such as AGC mode, switchable LNB-supply and a 10 MHz reference signal port are optionally available. The HQR145C 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).
