Objectives
The objective of the activity is to design channel filters for compact Ku-band input multiplexers using pre-distortion and lossy circuit techniques, with the objective of 25% reduction in terms of mass and size. Breadboards for the filters have been designed and characterized. In a second step, channel filters (EMs) have been built and tested for a narrow band and a wide band channel filter to evaluate the developed concepts and demonstrate the technology. Finally, limitations in key performance parameters against the mass and size improvement have been analyzed with respect to conventional un-predistorted Ku-Band IMUX channel filters.

Challenges
The key issues are:
– Realization of pre-distorted transfer functions
– Implementation of the transfer functions with low-Q & small-dimensions resonators.
Plan
The project has been successfully completed as of December 2015.
Current Status
The project has been successfully completed.
