Summary:The invention relates to a millimeter wave switch circuit based on impedance matching and an impedance adjusting method. The circuit comprises a power amplifier, a low noise amplifier and a millimeter wave switch module. The power amplifier is respectively connected with the millimeter wave switch module and external equipment, the low-noise amplifier is respectively connected with the millimeter wave switch module and the external equipment, the millimeter wave switch module is connected with an external load, and the millimeter wave switch module forms conjugate matching with the input end of the low-noise amplifier when the low-noise amplifier works. The millimeter wave switch module forms conjugate matching with the output end of the power amplifier when the power amplifier works normally. Impedance matching is formed among the millimeter wave switch module, the power amplifier and the low-noise amplifier, so that the switch does not consume power, the output power of the power amplifier is improved, the
