Description
Summary:This paper presents the designs, calculated by means of finite element method simulations characteristics and proposes fabrication process of a shunt and a series capacitive RF MEMS switches. Instead of traditional dielectric materials ultrananocrystalline diamond (UNCD) is used as an insulator layer of capacitive switches. These switches demonstrate isolation around 19-20 dB and loss around 0.3-0.4 dB at 10 GHz. The switches are candidates for high power microwave applications with high reliability due to unique charging characteristics of UNCD films.
