Radio frequency control circuit of base station of mobile communications systems

摘要: The radio frequency control circuit of the base station a mobile communications system is constructed in manner that transmitting coupler branching transmission signal to shadow region connected between side power amplifier and antenna, receiving inserting received from low noise splitter, cover using simplified configuration without separate hardware. Therefore, transmitted by optical antenna located at long distance through cable, dispersion close range coaxial provide radiocommunication service establishing region.
