More and more Ka-Band high power output multiplexer (OMUX) applications are requested on the Satellite market. The existing Ku-Band temperature compensation techniques for high power wave guide filter, manifolds and OMUXes cannot simply be scaled to the Ka-Band dimensions due to the higher sensitivity to the mechanical tolerances and to a temperature range increased by the higher dissipation of Ka-band filters.
In order to develop compensation techniques, which are adapted to Ka-band filters a detailed investigation and review of existing compensation techniques, as well as the development of more sophisticated and adapted temperature compensation techniques are needed.
The objective of the project is to develop a temperature compensation technique for both high power OMUXs and manifolds at Ka-band.
Compensation techniques shall be demonstrated on Ka-band filter (breadboards) and applied to a 3 channel contiguous OMUX (engineering model), with a long compensated manifold.
