Open the CIPO recordAbstract From the Canadian patent
An integrated radio frequency (RF) coupling scheme is provided for realizing low voltage RF integrated circuits. According to the invention on-chip capacitively, coupled resonant elements are used to DC isolate circuit block elements which are required to be connected in series and share a common DC current. The coupling scheme according to the present invention may be applied to several commonly used RF integrated circuit topologies such as low noise amplifiers and mixers.

Why it's free to use
- Filed December 16, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 16, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 16, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
