Open the CIPO recordAbstract From the Canadian patent
An orthomode transducer between a circular waveguide and two coaxial cables consists of a circular waveguide section, into which penetrate two probes externally connected to coaxial connectors. The probe placed closest to an input aperture at one end of the waveguide is tuned by a screw and by a metal plate in the same axial plane as the probe and, the other probe is tuned by a screw and a circular disc which closes the other end of the waveguide. The plate and the probes are shaped to optimise power coupling between the optical guide and the coaxial lines over a wide operating frequency band.

Why it's free to use
- Filed May 21, 1991 and granted December 6, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 21, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 21, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
