Benefits of technology

[0056]Another aspect of the present invention is to provide a TDD switch that protects the receive port even when the TDD wireless communication system abnormally operates due to errors

Problems solved by technology

The reception signal itself has a significantly low power level due to attenuation and noise.
As described above, the TDD switch of FIGS. 2A and 2B has a problem in that it cannot be separated by the circulator when errors occur in the antenna port (i.e., a signal is not properly radiated through the
