Electromechanical modelling of high power RF-MEMS switches with ohmic contact

This paper presents a study of the behaviour of electrically actuated RF-MEMS switches with ohmic contact. We discuss about the relationship between the actuation voltage, displacement and the corresponding contact force experienced by the switch. We demonstrate the linear behaviour of the switch when factors such as width or length of the switch arm are varied. Experimental results for DC actuation are also presented.
