It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 to 4, a KU band up-converter assembly includes a waveguide port 1, a waveguide 2, a circuit board 3, a signal output head 4 and an aluminum alloy shielding cover 5, the waveguide port 1 is horn-shaped, one end of the waveguide port 1 with a smaller diameter is communicated with the waveguide 2, the waveguide 2 is far away from one end of the waveguide port 1 is provided with an installation part 21, the circuit board 3 is installed in the installation part 21, the signal output head 4 is communicated with the installation part 21, the inner side of the installation part 21 is provided with a sliding groove 211, the aluminum alloy shielding cover 5 is L-shaped and is composed of a bottom sheet 51 and a close cover 52, the edge of the close cover 52 corresponds to the sliding groove 211, the sliding groove 211 is provided with a convex edge 521, and the bottom sheet 51 is connected with the bottom of the waveguide 2 through a bolt. Specifically, in this embodiment, the waveguide port 1 and the waveguide 2 are both made of metal, the waveguide port 1 is in a horn shape, so that the signal receiving performance is better, and meanwhile, in order to improve the anti-interference capability of the waveguide port 1 for clutter, a stepped convex edge may be further disposed in the waveguide port 1, and the waveguide 2 with a square cavity is matched to filter clutter. An installation part 21 is arranged at one end of the waveguide tube 2 and used for placing the circuit board 3, and electronic components such as a signal receiving antenna, an amplifier, a coupler, a band-pass filter and the like are integrated on the circuit board 3 and used for receiving signals and outputting the signals to the set top box through a signal receiving head 4 to complete the signal receiving processing work of the KU wave band.
