    Abstract: A waveguide able to operate at frequencies above 20 GHz is embedded in a printed wiring board. The waveguide is formed by evacuating a waveguide path through one or more dielectric layers of the board and joining the layers. After the layers are joined, the waveguide cavity is electroless copper plated by providing an electroless plating solution in the cavity. Thereafter, the cavity walls are electroplated to form seamless electrically conductive walls for the waveguide. A dielectric may also be provided in the cavity if desired. Electronic components may be formed in the waveguide by evacuating one or more layers of a printed wiring board in a similar manner, interconnected to the waveguide. In one embodiment, the components may convert the frequency of the signal carried in the waveguide so that higher frequency signals are processed within the RFI EMI protection of the layers of the wiring board.

    Abstract translation: 能够在高于20GHz的频率下操作的波导被嵌入在印刷线路板中。 波导通过将波导路径排出穿过基板的一个或多个电介质层并连接该层而形成。 在层被连接之后,通过在空腔中提供化学镀溶液,波导腔通过化学镀铜。 此后,将腔壁电镀以形成用于波导的无缝导电壁。 如果需要,还可以在腔中提供电介质。 可以通过以与波导相互连接的类似方式抽空一层或多层印刷电路板,在波导管中形成电子部件。 在一个实施例中,组件可以转换波导中承载的信号的频率,使得在布线板的层的RFI EMI保护内处理更高频率的信号。
