FRONT-END APPARATUS OF WIRELESS TRANSCEIVER USING RF PASSIVE ELEMENTS
First Claim
1. A front-end apparatus of an RF transceiver using radio-frequency passive elements, comprising:
- a plurality of band pass filters configured to band-pass filter a transmission signal and a reception signal in transmission and reception frequency bands corresponding thereto, respectively;
a first circulator configured to output a first transmission signal input into a first terminal to a second terminal and output a second reception signal input into the second terminal to a third terminal;
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 with circulators provided in four input/output terminals, respectively;
a first antenna configured to transmit the first transmission signal switched through the passive directional double pole and double throw switch to a wireless channel; and
a second antenna configured to transmit the second transmission signal switched through the passive directional double pole and double throw switch to the wireless channel.
