This paper presents a novel design of single-pole four-throw (SP4T) RF-MEMS switch employing both capacitive and ohmic switches. It is designed on high-resistivity silicon substrate and has a compact area of 1.06 mm(2). The series or ohmic switches have been designed to provide low insertion loss with good ohmic contact. The pull-in voltage for ohmic switches is calculated to be 7.19 V. Shunt o...

This paper signifies a very basic design and simulation techniques of RF MEMS switches using the advanced design systems software tool (ADS).Micro electro mechanical systems are recent development technologies which has better characteristics performance and also operating at microwave range of frequencies. Fundamentally MEMS switches can be categorized into two types series switches (ohmic typ...

Radio Frequency Micro-Electro-Mechanical-Systems (RF MEMS) based switches are expected to play a key role in the field of microwave switching. Traits like low-loss performance; zero-power consumption and very low inter-modulation distortion have made these switches well suitable for high-performance microwave and millimeter-wave circuits. The design of RF MEMS switches, however, require sophist...

A low actuation voltage RF MEMS shunt capacitive switch has been designed and simulated for use in X-band (8-12GHz) applications. The MEMS switch is a freely moving membrane over coplanar waveguide. Double meander structure of tuned dual beam is used here to improve the isolation of switch. Actuation is achieved by using electrostatic mechanism because of its low power consumption, small size a...

This paper describes the significance of iterative approach and structure damping analysis which help to get better performance validation shunt capacitive RF MEMS switch. The micro-cantilever based electrostatic ally actuated switch is designed after multiple iterations on cantilever a modification obtained that requires low actuation voltage 7.3 V for 3 ?m deformation. To validate we have per...
