<p>A waveguide matching unit is disclosed. The waveguide matching unit includes a gyrator having first and second waveguides. The first waveguide includes first and second ports that are connected by a first waveguide channel. An RF signal propagating through the first waveguide channel is phase shifted by about 90 when propagating from the first to the second port, and is phase shifted by about 0 when propagating from the second port to the first port. The second waveguide includes third and fourth ports that are connected by a second waveguide channel. An RF signal propagating through the second waveguide channel is phase shifted by about 0 when propagating from the third to the fourth port, and is phase shifted by about 90 when propagating from the fourth port to the third port.</p> |
