Abstract

The present invention provides a feed-forward pot integrated KU-band high-frequency head, which includes a head, a wave collector, a waveguide, a circuit box and an adapter. The lower end of the head is connected to the upper end of the wave collector, and the wave collector The lower end of the waveguide is connected to each other into one body, and the circuit box and the side wall of the waveguide are connected to each other into one body; a circuit board is installed in the circuit box; The integrated structure of the wave guide, the waveguide and the circuit box is made of aluminum alloy or magnesium alloy by one-time die casting, the head is made of aluminum alloy or magnesium alloy material, and the support part is made of PP plastic. The high-frequency head is simple in structure and low in cost; and its signal will not cause signal loss during transmission.

Description

technical field [0001] The invention relates to the field of devices for receiving satellite signals, in particular to a KU-band high-frequency head integrated with a positive feed pot. Background technique [0002] The function of the high frequency head dedicated to the positive feed pot is to amplify the signal received from the satellite, and to process the image deformation and interference caused by the unstable transmission. The existing high-frequency heads for positive feed pots generally include a head (secondary reflection part), a support part, a horn-shaped interface (commonly known as a wave collector), a circuit board part, and a waveguide part between the circuit board and the wave collector. . The wave collector and the waveguide are integrated, and the circuit board part and the waveguide are separate structures. In the actual application process, the high-frequency head of this structure often has the following disadvantages: the waveguide and the circui...
