This advanced electrostatic actuation similarly induces a very short switching time of around 2μs. Another strong advantage of DelfMEMS switch structure is the possibility to have a reduced gap between the membrane and the transmission line, which will reduce the creep and mechanical stress by lowering the maximum deflection of the membrane. This results in an increased contact force in ON-state with lowered actuation voltage and therefore lower insertion losses. Thanks to this novel and innovative approach, DelfMEMS RF MEMS switch is also able to look at a market where other RF MEMS solutions haven’t been considered yet: antenna switching. Among key requirements for true LTE-A compliant mobile devices are: higher data rate speeds and capacity, longer battery life and better signal reception quality. The solutions to achieve those goals are reduction of RF-FE component losses, introduction of high frequency bands, extension of DL & introduction UL carrier aggregation and improved band-to-band and Tx /Rx Isolation. DelfMEMS’s RF MEMS switch solution with 0.25dB insertion loss and 40dB isolation above 2 GHz and its IIP3 linearity above 90dBm for high-throw-count switches makes this component a perfect candidate to achieve those LTE-A goals, replacing existing solid-sate switching technology in applications where high frequency, ultra-high linearity and isolation and very low insertion loss are needed.
