HQS Series

L-Band Line Amplifiers with internal 1:8 or 1:16 Splitter


The HQS series represents variable gain L-Band amplifier units with integrated 1:8 or 1:16 splitters. The variable gain line amplifier modules supports gain-control ranges of max. 0...25dB or 0...30dB. The 19"/1RU rack-mount chassis „HQS108C“ (1:8 splitter chassis) and „HQS116C“ (1:16 splitter chassis) each with one amplifier slot allow insertion of the the corresponding amplifier module HQA2535M“ or „HQA3040M“. The „HQA2535M“ amplifier allows variable gain-control of max. -10...15dB @ standard gain mode and max. 0...25dB @ high gain mode while the „HQA3040M“ amplifier provides variable gain-control of max. -10...20dB @ standard gain mode and max. 0...30dB @ high gain mode so to achieve best signal performance within the network. The HQS series features variable gain-control (MGC/AGC), slope equalization, RF power monitoring, switchable LNB-supply, a 10MHz external reference signal input and 1:1 redundant dual power-supply (hot-swappable). An integrated RF power detector measures the RF output power with 70dB dynamic range. The units have a front side LC-Display/keypads for user-friendly local configuration while front side status LED´s indicating amplifier and power-supply status. Remote configuration & monitoring can be done via its rear side Ethernet-Interface (WebGUI, SNMP). This high quality HQS splitters togehter with the inserted line amplifier module provide various advantagous functionalities, superior RF performance and excellent signal quality. The HQS units are excellent for compensation of passive RF distribution devices and cable loss and suited for versatile application areas (Teleports, Earth Stations, Broadcast operations...) assuring accurate RF power, highest signal stability and availability.
