Open the CIPO recordAbstract From the Canadian patent
Several MEMS-based methods and architectures which utilize vibrating micromechanical resonators in circuits to implement filtering mixing, frequency reference and amplifying functions are provided. A method and subsystem are provided for processing RF signals utilizing a plurality of vibrating micromechanical devices typically in the form of an IF mixer-filter and an RF channel selector or an image-reject RF filter. One of the primary benefits of the use of such architectures is a savings in power consumption by trading power for high selectivity (i.e. high Q). Also such methods and , circuits can elimitate the need for a low noise amplifier in a receiver or transceiver subsystem. …

Why it's free to use
- Filed April 20, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 20, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 20, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
