A waveguide matching unit is disclosed. The waveguide matching unit includes 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.
