摘要：
A bi-directional signal interface includes a first waveguide that propagates a first traveling wave. The first waveguide has one end that is coupled to a RF input port that receives a RF transmission signal and another end that is coupled to a RF bi-directional port that receives a RF reception signal and transmits the RF transmission signal. A second waveguide is positioned proximate to the first waveguide. The second waveguide has one end coupled to an output port that passes the received RF reception signal. A non-reciprocal coupler couples fields from the first waveguide to the second waveguide so that the RF reception signal from the bi-directional port couples from the first waveguide to the second waveguide in a substantially non-reciprocal manner and then passes through the output port, and the RF transmission signal from the RF input port passes through the first waveguide to the RF bi-directional port.
摘要（中）：
双向信号接口包括传播第一行波的第一波导。 第一波导的一端耦合到接收RF传输信号的RF输入端口，另一端耦合到接收RF接收信号并传输RF传输信号的RF双向端口。 第二波导被定位成靠近第一波导。 第二波导的一端耦合到传送接收到的RF接收信号的输出端口。 非互易耦合器将来自第一波导的场耦合到第二波导，使得来自双向端口的RF接收信号以基本上非互易的方式从第一波导耦合到第二波导，然后穿过输出端口 ，并且来自RF输入端口的RF传输信号通过第一个波导到达RF双向端口。
