Description:

PIEZOELECTRIC MEMS RESONATOR TECHNOLOGY WITH INTEGRATED PHASE CHANGE MATERIAL SWITCHES

INV-14097

INVENTORS:  Matteo Rinaldi, Gwendolyn Hummel

Description       

Fabrication of conventional electromechanical switches is a complex procedure requiring assembly of multiple components and shopping various vendors.  Such switches require a higher voltage (35-40V) to program, along with a requirement for creation of micro/nano gaps.  Moreover, till date, the potential integration of these switches with piezoelectric resonators has not been very feasible.  This invention relates to a novel piezoelectric MEMS resonating system with integrated phase-change material switches having low ON resistance (~5Ω), large ON/OFF ratio (~107), and low OFF capacitance (~40fF), overcoming prior art limitations and/or unmet needs.

 

Value Proposition

The system:

•Is highly compact and miniaturized

•Requires a much lower voltage (1-2.5V) to program

•Is capable of effectively operating at multiple frequencies

•Has a simpler fabrication, making it highly cost effective

•Avoids use of power to keep the switch in either of the states (ON or OFF)

•Has a higher performance as compared to conventional systems

•Has a much reduced development cost as compared to conventional multi-band radios

•Effectively eliminates the necessity of shopping vendors for different frequencies

•Has a reduced component count as compared to conventional systems, allowing programming of the system even without additional RF elements such as capacitors

•Uses phase-change switches that doesn’t require creation of micro/nano scale gaps as observed with conventional switches

•Has reconfiguration functionalities, capable of operating in severely crowded and rapidly changing modern commercial and military spectral environment

•Would be commercially useful for:

oImplementation of high performance RF wireless communication

oFabrication of filter platforms

oVarious radio front-end applications

oAmateur Home Radio Setups
