Strong I/O Coupled High-Q Micromechanical Filters [BPN682]
This project will use the high-Q design techniques of traditional capacitive resonators to
demonstrate novel low impedance (10-1000 Ohm) and high-Q (Q>10,000) resonators at VHF and UHF
frequencies, that are mechanically coupled, to realize 2nd and 3rd order channel-select filters with
fractional bandwidths of 0.1-1%, insertion losses of less than 2-dB and that can handle high out-of-
band and in- band power. These filters will be implemented using capacitive-piezo AlN technology, to
achieve higher Q’s than those achievable using traditional AlN technology with contacting
electrodes, while maintaining reasonably low impedance in a small form factor.
