摘要:
The invention relates to the provision of LNB apparatus alone and/or in conjunction with a waveguide which is provided to process received data signals which are broadcast using satellite transmission systems. The wanted data signals are passed along at least two paths formed on the printed circuit board structure provided in the LNB. The printed circuit board structure includes at least one integrated circuit with an image rejection mixer or direct conversion mixer which allow the filtering out of the unwanted frequency bands from the received data. The printed circuit board is formed with at least two, but most typically three, conductive material layers in which the data paths are formed. The first and second conductive layers are spaced apart by a single packer layer substrate and the second and third conductive layers are spaced apart by a single packer layer structure or by a substrate formed of a plurality of layers to allow the manufacture of the printed circuit board structure to be economical whilst allowing the quality of the data signals provided to be at least maintained. The connection between the waveguide and LNB is tuned at the waveguide with respect to the impedance values.
