WAVEGUIDE INTERFACE AND PRINTED CIRCUIT BOARD LAUNCH TRANSDUCER ASSEMBLY AND METHODS OF USE THEREOF

A printed circuit board assembly comprising a plurality of layers. At least one of the plurality of layers is formed of a dielectric material and has an extended portion extending beyond the other layers in the plurality of layers. A first metallic layer is located on at least a portion of the extended portion of the dielectric layer. The first metallic layer and the dielectric layer are configured to form a launch transducer comprising one or more transmission lines and a transducer element coupled to the one or more transmission lines. The transducer element is configured to propagate millimeter wave frequency signals. 一种印刷电路板组件，包括多个层。多个层中的至少一层由电介质材料形成，并且具有延伸超过多个层中的其他层的延伸部分。第一金属层位于电介质层的延伸部分的至少一部分上。第一金属层和电介质层被构造成形成发射换能器，该发射换能器包括一条或更多条传输线和换能器元件，该换能器元件耦接至该一条或更多条传输线。该换能器元件被构造成传播毫米波频率信号。
