Novella supplies frequency converter redundant systems in 1:1 up to 1:8 configurations. These systems may be of frequency agile or block converters.

The simplest 1:1 redundant system consists of a RU03 unit with two coaxial switches mounted on the rear panel. This system has the advantages of low insertion losses and very good isolation between master and slave signal paths. This system may be used with agile or block converters.

Novella supplies also a simple 1:2 system suitable only for block converters. Two sets of three coaxial switches allow a third block converter to function as spare for two master block converters. This configuration is ideal for dual polarisation up or downlinks with L-band interface.
