Radio-frequency switch control link and system and control method therefor

A radio-frequency switch control system, comprising a radio-frequency switch control link and a radio-frequency switch,

• wherein the radio-frequency switch control link comprises:
• an input port, configured to input an original signal;
• an edge detection module, wherein an input end of the edge detection module is connected to the input port, and a control end of the edge detection module is connected to a control signal, and the edge detection module is configured to output a boost-mode signal when the control end is connected to a boost control signal and output a normal-mode signal when the control end is connected to a normal control signal;
• and
• a bias voltage generation module, comprising a first oscillator and at least one stage of a charge pump, wherein the charge pump and the first oscillator are both connected to an output end of the edge detection module;
• the first oscillator is configured to output a first frequency in response to the boost-mode signal, and output a second frequency in response to the normal-mode signal, wherein the first frequency is greater than the second frequency;
• the charge pump comprises a pump capacitor unit, and the pump capacitor unit is configured to have a first capacitance value in response to the boost-mode signal, and have a second capacitance value in response to the normal-mode signal, wherein the first capacitance value is greater than the second capacitance value.
