A ladder structure composed of contour-mode Aluminum Nitride piezoelectric resonators is used to form low insertion loss bandpass filters. These devices can be designed to control their bandwidth and center frequency, allowing for multiple filters operating on different bands to be fabricated size by side. This integration allows for filters to be constructed 20x smaller than existing surface acoustic wave resonator based devices.
The CMOS-compatible fabrication process could allow smaller filters and duplexers to be fabricated directly onto chips, reducing the size of mobile networked devices, and adding key value for Internet of Things devices.
