In this paper we present a new type of RF MEMS switch, for low actuation voltage, high RF power and high reliability applications in telecommunication. ‘Symmetric Toggle Switch’ (STS) is based on push – pull mechanism and utilizes torsion springs and levers, placed symmetrically and transverse to CPW RF signal line. The switches designed for 3 to 10 GHz pplications have analytically calculated and FEM simulated actuation voltages in the range of 5 to 10 volts. The EM simulated insertion loss and isolation for devices (in fabrication) are 0.25 dB and 27 dB respectively at 5 GHz

In this paper we present a new type of RF MEMS switch, for low actuation voltage, high RF power and high reliability applications in telecommunication. ‘Symmetric Toggle Switch’ (STS) is based on push – pull mechanism and utilizes torsion springs and levers, placed symmetrically and transverse to CPW RF signal line. The switches designed for 3 to 10 GHz pplications have analytically calculated and FEM simulated actuation voltages in the range of 5 to 10 volts. The EM simulated insertion loss and isolation for devices (in fabrication) are 0.25 dB and 27 dB respectively at 5 GHzFile in questo prodotto:
