Designers of satellite communication systems can help to prevent disruption to signal transmissions by using a range of redundant line amplifiers now available from Link Microtek.

Manufactured by US company MITEQ, the robustly constructed

lm461 medium Outdoor redundant line amplifiers ensure continuous operation of satcom systems in a choice of 1:1, dual 1:1 or 1:2 configurations.

In the event of a fault condition or when initiated by an operator-generated command, the system automatically switches the standby amplifier into the satcom link while removing the original amplifier from the signal path, thereby ensuring continuous operation.

The RL-W systems can be specified with 17 different satcom bands covering frequencies from 950MHz to 33GHz. Performance figures for the standard units are a 30dB minimum gain and a +10dBm minimum power output (at 1dB compression), and these can be optionally uprated to 40dB/50dB and +15dBm/+20dBm if required.

Remote control is provided as standard via a user-selectable RS485/RS422 interface, while contact-closure, RS232 and 10/100Base-T Ethernet interfaces are also available as options.

All versions feature a wide input voltage range of 90-250VAC and use fully redundant, hot-swappable power supplies with independent AC inputs to maximise system availability.
