초록
Disclosed is a front-end apparatus of an RF transceiver connected with an antenna in a wireless communication system. The front-end apparatus of an RF transceiver using radio-frequency passive elements includes: a plurality of band pass filters configured a transmission signal and a reception signal; a first circulator configured to output a first transmission signal to a second terminal and output a second reception signal input; a second circulator configured to output a second transmission signal input into the first terminal to the second terminal and output a first reception signal input into the second terminal to the third terminal; a passive directional double pole and double throw switch configured to process a route to be changed depending on directions of an input and an output; a first antenna configured to transmit the first transmission signal; and a second antenna configured to transmit the second transmission.
