[0078] Similarly, microwave signal 2 is input from terminal A2 of the microwave signal distribution component and split into two paths by the internal power divider. The first path outputs from terminal B2 to the input terminal A2 of the dual-path downconverter component, providing the local oscillator input signal for the dual-path downconverter component. The microwave signal input from terminal A0 of the dual-path downconverter component is amplified and mixed with it to achieve downconversion of microwave signal 2. After passing through the internal power divider, one path outputs from terminal B3, and the other path goes to the input terminal A2 of the switching component, serving as one input signal for a 4-to-4 switch. After being selected by this switch, it can be output from one of the four output terminals B1, B2, B3, and B4. The other path passes through the 3-to-1 switch K1 of the microwave signal distribution component and outputs to the input terminal A3 of the switching component. After being selected by this switch, it can be output from one of the four output terminals B1, B2, B3, and B4.
[0079] Microwave signal 3 is input from terminal A3 of the microwave signal distribution component to the input terminal of switch K2.

[0082] High-frequency signal 3 is input from terminal A3 of the high-frequency signal distribution component, and is split into two paths by the internal power divider. One path is connected to terminal B3, and the other path is output to one input terminal of the four-to-one switch K3. After being selected by K3, it is output from terminal B0 of the high-frequency signal distribution component to input terminal A4 of the switch component. After being selected by the switch, it can be output from one of the four output terminals B1, B2, B3, and B4.
[0083] High-frequency signal 4 is input from terminal A4 of the high-frequency signal distribution component. It is split into two paths by an internal power divider. One path connects to terminal B4 and outputs to input terminal A1 of the high-frequency signal conversion component. After passing through the power divider and a 6-way divider, the signal at 1 / 6 of its frequency is input to the output power divider within the component, splitting it into two groups of signals. These are then output through terminals B2 and B3 of the component. The other path outputs to one input of a four-to-one switch K3. After being selected by K3, the signal is output from terminal B0 of the high-frequency signal distribution component to input terminal A4 of the switch component. After being selected by this switch, the signal can be output from one of the four output terminals: B1, B2, B3, or B4.
