The FlexLink-K4 is a professional, flexible and scalable L-Band Switch Matrix in 4RU/19″ rack mount design supporting Extended L-Band frequency range (850 – 2450MHz), useable for standard L-Band, KA-Band and HTS applications. It allows various switch/routing configurations from 4:4 to 32:32 (increments of 4) where one input can be switched/routed to one or all outputs (fan-out/distributive). The system comes in two versions, the K4-Eco and the K4-Plus both available with max. 32 inputs and 32 outputs. The K4-Eco system is a standard unity gain matrix while the K4-Plus comes with additional features such as variable gain-control, slope equalization, RF power monitoring and optionally with LNB-supply and 10MHz external reference signal port.
