This ensures that all received frequency bands are processed and analyzed in a time-sharing manner with a single receiving antenna. The signal collection of each frequency band is achieved through high-speed switch switching control by the control unit (i.e., the second controller). At the same time, the link design of the signal switch solves the problems of high engineering design difficulty and high antenna cost for installing multiple antennas. At the same time, time-sharing reception does not affect the analysis of existing network signals, and time-sharing reception avoids the situation where signals generated by receiving signals of different frequency bands at the same time are coupled with each other, resulting in signal distortion. After the signal passes through the switch, it is filtered and selected for different frequency bands. After filtering, it is combined through the radio frequency signal switch, and then power amplification is performed. The reused power amplification module and gain adjustment module make the design more reusable, and the design difficulty and cost are greatly reduced. At the same time, the circuit design scheme ensures that a single hardware interface can realize signal reception and analysis of multiple frequency bands in the existing network, greatly reducing the hardware development cost of the back end.
