[0023] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0024] In the prior art, the length and width of the circuit board 2 are generally 3-5 mm. The circuit board 2 is generally screwed to the housing 1 using surrounding screws. Since the screwed portion of the circuit board 2 has no other use except for the screwed purpose, this causes the circuit board 2 to be 1-2 mm larger than the practical part. In addition, since the components on the circuit board 2 are generally packaged only in the housing 1, the components will occupy too much circuit volume, making the layout of the miniaturized circuit board 2 more difficult. In addition, the connecting lines between the components on the circuit board 2 are generally arranged in a curved manner, which will cause greater transmission losses when the microwave signal is transmitted.
[0025] The present application provides a Ku up-conversion component to solve the above technical problems.

[0026] Among them, the first constant and the second constant can both be 0.7, and the ratio of the length and width of the circuit board 2 of the Ku upconverter to the length and width of the housing 1 is less than a certain value, which can ensure that the volume of the circuit board 2 of the Ku upconverter is smaller than the volume of the circuit board on the market, thereby improving the integration of components of the circuit board 2. It should be noted that the length and width of the housing 1 mentioned here refer to the average length and width of the housing 1 used by all Ku upconverter components on the market. The circuit board 2 can be a PCB circuit board.
[0027] Specifically, the Ku up-conversion component processes the input first pumping signal and the second pumping signal through the first mixing circuit 3 and the second mixing circuit 4, respectively, to obtain the corresponding first RF signal and the second RF signal. The first mixing circuit 3 and the second mixing circuit 4 are connected to the first output circuit 5 and the second output circuit 6 through the first switch 7 and the second switch 8, respectively. The first output circuit 5 processes the first RF signal selected by the first switch 7 to obtain the first RF sub-signal; the second output circuit 6 processes the second RF signal selected by the second switch 8 to obtain the second RF sub-signal; the first RF sub-signal and the second RF sub-signal are selected by the third switch 9 to output the third RF signal. The embodiment of the present application uses a plurality of straight microwave lines to connect the first mixing circuit 3, the second mixing circuit 4, the first output circuit 5, and the second output circuit 6, shortening the length of the connecting lines of each circuit, thereby reducing the loss of the signal during transmission.
[0028] Exemplarily, the first pump frequency signal and the second pump frequency signal can both be two 720MHz output signals from the signal processor.

The second subcircuit 5-2 and the third subcircuit 6-1 are connected to the test signal output terminal 22 after being aggregated by the power divider 12. After the test signal output terminal 22 reaches the conductive layer of the circuit board 2 by punching and changing layers, it bypasses the first output circuit 5 located on the surface of the circuit board 2, and then punches and changes layers to the surface layer, and is connected to one end of the test signal output line 21, and the other end of the test signal output line 21 is connected to the first output interface 13.

[0032] Specifically, the second output interface 14 is disposed on the second side wall of the circuit board 2, and the first side wall and the second side wall are opposite to each other, thereby improving the space utilization of the circuit board 2. The test output signal and the RF output signal are separated from each other, thereby reducing interference between them.
[0033] In an embodiment of the present application, the Ku up-conversion component may also include a third output circuit 15 and a fourth output circuit 16, wherein the input end of the third output circuit 15 is connected to the output end of the first mixing circuit 3; the input end of the fourth output circuit 16 is connected to the output end of the second mixing circuit 4; the output ends of the third output circuit 15 and the fourth output circuit 16 are both connected to the fourth switch 23, and the fourth switch 23 is connected to the third output interface 17 through the verification signal output line; the third output interface 17 is located on the third side wall of the circuit board 2, and the third side wall is connected to the first side wall and the second side wall; the third output circuit 15 is used to process the first RF signal selected by the first switch 7 to obtain a first check sub-signal; the fourth output circuit 16 is used to process the second RF signal selected by the second switch 8 to obtain a second check sub-signal; the first check sub-signal and the second check sub-signal are selected by the fourth switch 23 and output a calibration signal through the third output interface 17.

Moreover, the straight microwave lines are arranged according to the signal flow, and the orthographic projections of the straight microwave lines on the bottom layer will not overlap, thereby avoiding mutual interference of signals.

[0036] It should be noted that two adjacent straight microwave lines at right angles can minimize the bending of the microwave lines, thereby minimizing the loss. The straight microwave lines connecting various circuit components have very few right angles except for necessary bends, which can further avoid signal loss.
