A range of redundant block converter systems are now available from Link Microtek that can help improve performance for commercial or military satcom services. This is archived by the devices’ capability to deliver continuous operation in the event of a fault condition, with automatic switchover and no loss of signal.
The devices are manufactured by US company MITEQ Inc. and are known as RB-WS systems. They are made up of an outdoor antenna-mount assembly, an indoor rack-mount control unit and either one or two 30m-long interface cables, depending on the configuration of the system.
The single-plate weather-resistant assembly is a fully integrated unit, incorporating switching elements, controller interface and block converters to provide redundancy in 1:1, dual 1:1 or 1:2 configurations. A wide range of upconverter and downconverter assemblies is available, covering the C, X, Ku, K and Ka satcom frequency bands. All models have an operating temperature range of -40 to 60degC.
Monitoring and control of the converters is handled by the 1U-high 19in. rack-mount control unit, which features an input voltage range of 90-250VAC and fully redundant, hot-swappable power supplies to maximise system availability. The unit can be used for either automatic or manual control, and both 10/100Base-T Ethernet and RS485/RS422 interfaces are provided for remote control and status monitoring.
Available options for the RB-WS system include input/output signal monitors and custom-length interface cables.
