Abstract: The present invention generally relates to an architecture for isolating an RF MEMS device from a substrate and driving circuit, series and shunt DVC die architectures, and smaller MEMS arrays for high frequency communications. The semiconductor device has one or more cells with a plurality of MEMS devices therein. The MEMS device operates by applying an electrical bias to either a pull-up electrode or a pull-down electrode to move a switching element of the MEMS device between a first position spaced a first distance from an RF electrode and a second position spaced a second distance different than the first distance from the RF electrode. The pull-up and/or pull-off electrode may be coupled to a resistor to isolate the MEMS device from the substrate.

Abstract: The present disclosure generally relates to a device having a variable frequency filter that rejects harmonics generated by a variable reactance device. The variable frequency filter may be coupled to the antenna and the variable reactance device. The filter includes a variable capacitor and an inductor coupled together as a resonant circuit. The filter may be used in cellular technology to prevent harmonic frequencies that are created by another variable reactance device from reaching the antenna of the cellular device. Furthermore, the filter can reflect any receiving frequencies from the antenna and prevent the receiving frequencies from passing through.
