Addressing reconfiguration of radio frequency (RF) systems might require high performance integrated RF switching capabilities. In this regard, a particular design experience of an integrated circuit (IC) monolithically integrated microelectromechanical systems (MEMS) ohmic switch is reported here. Applications at 2 GHz have been targeted.

A Comparison between RF MEMS Switches and Semiconductor Switches
2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04), 2004This paper addresses the fundamentals of RF switches providing a comparison between semiconductor and RF MEMS switches. The basis of comparison is introduced by defining a figure of merit that is a function of the off-state capacitance and the on-state resistance.

RF MEMS switches and switch circuits
IEEE Microwave Magazine, 2001MEMS switches are devices that use mechanical movement to achieve a short circuit or an open circuit in the RF transmission line. RF MEMS switches are the specific micromechanical switches that are designed to operate at RF-to-millimeter-wave frequencies (0.1 to 100 GHz).

2007 Asia-Pacific Microwave Conference, 2007
This paper reviews three novel RF MEMS ohmic contact switches, each being designed for specific applications. All three were developed at Imperial College London. The first is a packaged single-pole double throw (SPDT) version intended for space applications, operating from DC to 6 GHz; the second is a single-pole single throw (SPST) switch for high ...

RF-MEMS switches: paradigms of microwave switching
APMC 2001. 2001 Asia-Pacific Microwave Conference (Cat. No.01TH8577), 2002This paper reviews the most recent development of RF-MEMS switches in microwave and mm-wave frequencies up to 110 GHz W-band frequencies. RF-MEMS switches are categorised in different configurations such as cantilever, air-bridge and diaphragm with series and shunt configurations and resistive and capacitive contacts.

RF MEMS switch for wireless LAN applications
Proceedings International Conference on MEMS, NANO and Smart Systems, 2004Double cantilever beam MEMS switch was developed for wireless LAN applications. The two beams are controlled by a single actuation electrode. The dimension of the fabricated cantilever beam is 150 /spl mu/m /spl times/ 60 /spl mu/m /spl times/ 0.6 /spl mu/m. The spacing between the top beam and the bottom ground electrode was approximately 1 /spl mu/m.

Low Frequency Test for RF MEMS Switches
2010 Fifth IEEE International Symposium on Electronic Design, Test & Applications, 2010In order to envision fault-tolerant SiPs and SoCs containing RF MEMS switches, this paper studies easily embedded low frequency tests for capacitive switches. The correlation between high frequency (S parameters) and low frequency (envelope of the high frequency signal) responses of a capacitive RF MEMS switch is analysed.
