RF Design - RLA270L L Band Rackmount Amplifier, 1 x 1 redundant

Call for Price

The RLA270L represents a 1:1 redundant L-Band line-amplifier (950…2150MHz) featuring variable gain, slope- equalization, 10MHz external reference and LNB-powering all in a compact 1RU/19″ design. This 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. The RLA270L is equipped with two high dynamic 1:1 redundant operating amplifier-modules (hot-standby) each providing variable gain of max. 27dB so to achieve best performance within the network. The redundancy switching between the two amplifier-modules is done nearly interruption free within a switchover time of less than 5ms. The unit features adjustable gain (MGC/ AGC), slope-equalization, RF-power monitoring, 10MHz ref., LNB-powering and 1:1 redundant power-supply (hot-swappable). The RLA270L has a front-side LC-Display/keypads for user-friendly local configuration while front-side status LED´s indicating amplifier and power-supply status. Remote control and configuration can be done via its rear-side Ethernet-Interface (WEB-GUI, SNMP). The RLA270L is available with 50Ohm SMA(f) or 75Ohm F(f) connectors (see order-information).
