Ku-Band High Power Dielectric Resonator Filters

Abstract

In this paper, a novel dielectric-resonator filter configuration is presented. The new filter offers superior Q and wider spurious-mode free range at Ku-Band. Moreover, it offers 70% mass savings over the TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">114</sub> dual mode designs and over 50% footprint reduction compared with the TE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">113</sub> dual-mode implementations. These characteristics make this technology well suited for the output multiplexer used in Ku-Band satellite applications. A five pole filter has been implemented to prove the superior performance of this new technology. Test data over temperature and high power test results are also presented, including a 3-Channel output multiplexer.
