  • Abstract
    This paper presents the principle of operation and design equations of MEMS-based variable capacitors designed using the MUMPs technology. Two prototypes with different tuning characteristics are examined. Measurements have shown that a tuning range of more than 35% is achievable at 2.4 GHz, with a self-resonant frequency of 4 GHz, and a maximum quality factor of 15. An analysis of the performance obtained is discussed, in the context of the characteristics of the fabrication process used.
