PURPOSE: A transmission of a TDD mode and a transceiving switching method thereof for a bidirectional wireless communication of a microwave and RF signals are provided to perform high-power signal process by using low-priced switching element by processing transceiving switching. CONSTITUTION: A power amplifier(130) amplifies microwave and the transmitted high frequency signals. An LNA(Low Noise Amplifier)(140) amplifies and controls low noise of high frequency signals and the received microwave. If the power amplifier is connected, a first switch switches in order to operate the power amplifier. If the low amplifier is connected, a second switch switches in order to operate the lower power amplifier. |
