The invention belongs to the technical field of wireless communication and discloses a high power high speed radio frequency transmitting/receiving switching device and method and a wireless communication system. A bias voltage module is connected with a power amplifier through a power control switch. The power amplifier is connected with a PIN switch and an antenna in parallel. The PIN switch isconnected with a low noise amplifier in series. When transmission is carried out, the PIN switch is switched off, the power control switch is switched on, the bias voltage module is loaded to the power amplifier, and the power amplifier transmits a high power radio frequency signal. When receiving is carried out, the power control switch is switched off, the output of the power amplifier is switched to high resistance, no radio frequency signal is output, the PIN switch is switched on, and a received signal at the antenna end is coupled with the low noise amplifier, so the signal is received.According to the high powe
