Abstract: A signal transceiver apparatus, including at least one plug-in card and a backplane. The plug-in card includes two waveguide boards, a multi-layer circuit board disposed between the two waveguide boards, and an antenna array and a first waveguide interface that are mounted on each of the two waveguide boards. A waveguide slot is provided on one side, facing the multi-layer circuit board, of each of the two waveguide boards. A metal layer corresponding to the waveguide slot is disposed on each of two sides of the multi-layer circuit board. The “corresponding to” means that the metal layers and the waveguide slots cooperate to form two waveguide channels that are respectively located on two sides of the multi-layer circuit board and that each are connected to the antenna array and the first waveguide interface
