HI, EVERYONE. I want to use the whole ports of a coupler including coupled and isolated ports, as shown in figure. And All the ports of a coupler can be input port and output port. However, the coupler block from AWR has predefined input ports and output ports, for instance, coupled port is defined as a output port not a input port. When the coupled port is used as a input port, there will be a error. So i wanna find another way to achieve below network.
