2282-122-21 Redundant Amplifier, 0.95-2.15 GHz, +33 OIP3

The Model 2282-122-21 Redundant Amplifier, 0.95-2.15 GHz, +33 OIP3, monitors and controls internal amplifiers configured in a 1:1 or 1:2 redundant configuration. Variable attenuators can adjust the gain of each amplifier by 30 dB in 0.5± 0.5 dB steps by the front panel controls and the M&C. Front panel LEDs indicate power, status (online, standby, alarm), and mode (auto, manual, remote). The amplifiersʼ current is measured and a fault is signaled if the current deviates from user selected thresholds. Multi-function switches select Auto, Manual or Remote operation, priorities for 1:2, and the signal path in the Manual mode. Remote operation via the RS232/RS485 M&C interface allows selection of priorities (1:2) and the signal path. Ethernet is available as an option. An LCD display shows each amplifierʼs current, and Attenuation settings. Connectors are type N, female for the RF in and out signals, DB9 for monitor and control. The 2282-122-21 is housed in a 1RU chassis and is powered by redundant power supplies fed by separate, fused 100-240 ±10% VAC AC input connectors.
