Zelinda provides a complete design and build capability for radio communication subsystems, both terrestrial and spaceborne. This capability ranges from initial feasibility studies; simulation; design; prototype build and test through to subcontracted manufacture. Zelinda specialises in developing novel design solutions using digital processing to improve reliability, reduce size and mass as well as eliminating the need for "tuning" of analogue and RF circuits. These novel designs are often conceived during "paper" studies undertaken to review and extend the boundaries of currently accepted practice.
While the company expertise is concentrated in the design of digital demodulators by using a network of specialist subcontractors Zelinda is able to offer a service that encompasses RF design and build to ESA space-flight standards.
