WAVEGUIDE COMPONENTS

OVERVIEW

Waveguide components, which aim to transmit RF signals with low loss or which allows transmission of high power RF signals, are qualified for geostationary satellites.

Several different waveguide products with different characteristics are available with the possibility of customization according to specific customer or mission requirements. These products can be used to combine, filter or separate RF signals from each other.
