Ku-Band is the most widely used frequency band in the increasing field of satellite communications. In every satellite transponder, the input multiplexer (IMUX) is a crucial component. Therefore there is a well justified demand for the development of IMUXes beyond the present state of the art. The technology of choice is dielectric technology due to its small size, low losses and temperature compensation.
The objective of the project is to develop, build and qualify a Ku-band input multiplexer in dielectric technology with:
Key issues are:
Expected benefits brought by the project are:
Input multiplexers constitute a basic element in the payload of a telecommunication satellite. They connect a receive antenna to the channel amplifiers.
The project has 4 main phases:
The project has successfully been finished in April 2006. The equipment with the advantages envisaged has been successfully developed, built and qualified for space applications. A mass of less than 800g and a footprint of 104 x 141 mm^2 has been achieved for a 4-channel multiplexer including baseplate and input section.
