[0024] A removable shielding plate 4 is installed on both side surfaces of the electromagnetic shielding shell 1 through a card interface, and a multi-dimensional composite shielding layer cover is installed on the top of the electromagnetic shielding shell 1. The multi-dimensional composite shielding layer cover uses a high magnetic permeability Permalloy soft magnetic material in the innermost layer to absorb low-frequency magnetic field interference, a high conductivity copper metal in the middle layer to shield high-frequency electric fields, and a carbon-based absorbing material in the outermost layer to absorb and attenuate electromagnetic interference penetrating the first two layers.

[0025] In a specific scheme, first, at the signal input stage, the external multi-band mixed signal enters the phase shifter as a whole through the input end 2 of the electromagnetic shielding shell 1, and the electromagnetic shielding shell 1 and the removable shielding plates 4 on both sides and the multi-dimensional composite shielding layer cover on the top provide a good electromagnetic shielding environment for the internal components to prevent external electromagnetic interference from affecting signal processing.

The electromagnetic noise active suppression circuit board 101 at the bottom end of the electromagnetic shielding shell 1 monitors and suppresses the electromagnetic noise generated inside in real time to ensure the purity of the input signal.

[0026] Then, in the frequency band separation and preprocessing stage, the input signal is transmitted to multiple groups of frequency band adjustment units 103 through the high-speed wireless communication link 102. The frequency band adjustment unit 103 performs preliminary adjustment and screening on the signal according to the preset frequency band range.

[0028] Then, in the signal synthesis and output stage, the phase-adjusted signals of each frequency band are transmitted to the RF circuit 1092 through the output connection port 1098. The RF circuit 1092 further processes and optimizes the signals to ensure the quality and stability of the signals, so that the processed signals of each frequency band are transmitted to the signal synthesizer 1090. The signal synthesizer 1090 synthesizes the signals of each frequency band into a mixed signal, and makes the synthesized signal pass through the self-cancelling bidirectional control electromagnetic radiation circuit 1091, which monitors the electromagnetic radiation generated by itself in real time and generates a reverse radiation signal for cancellation, thereby reducing interference to the surrounding environment and other components.

[0029] At the same time, during the overall operation of the phase shifter, the adjustment is made according to the changes of the external signal. When the frequency band, strength, phase and other parameters of the external signal change, the adjustment factor controller 106 obtains these change information in real time through the data interaction and coordination unit 107, so that when it is detected that the signal strength of a certain frequency band suddenly increases, the adjustment factor controller 106 will recalculate the adjustment factor value of the frequency band and adjust the parameters of the variable RF element 1010 to ensure the phase adjustment accuracy and stability of the signal in the frequency band, or adjust according to the changes of the internal state, and use the giant magnetoresistance effect current sensor 1096 to monitor the magnetic field changes inside the phase shifter in real time. The electromagnetic noise active suppression circuit board 101 monitors the internal electromagnetic noise. When the giant magnetoresistance effect current sensor 1096 detects that the internal When the internal magnetic field or electromagnetic noise changes, this information will be fed back to the adjustment factor controller 106. The adjustment factor controller 106 adjusts the adjustment factor value according to this information, and adjusts the phase of each frequency band signal accordingly to adapt to the change of the internal state, so as to ensure the stable operation of the phase shifter. The application scope of the phase shifter is greatly expanded as a whole, so that signals of multiple frequency bands can be processed simultaneously, the efficiency and flexibility of signal processing are improved, and the influence of external electromagnetic interference on the internal components of the phase shifter is effectively reduced.
