"The next generation of mobile computing devices will require advanced radio frequency (RF) filter and oscillator banks covering multiple RF bands," said Roy H. Olsson III. "Our miniature acoustic resonators fill this need." Microresonators are small acoustic resonators that have highly precise sound and are manufactured using the same technologies that mass-produce integrated circuits (IC). Microresonator technology allows hundreds of filters and oscillators operating over a wide (32kHz - 10 GHz) frequency range to be realized on a single IC chip and monolithically integrated with radio frequency (RF) transistor circuits. They will perform RF filtering and frequency synthesis functions in next-generation wireless handsets, cell phones and other wireless devices, offering higher performance and frequency diversity in a smaller package and at a lower price than current technologies.
