DUPLEXER IN BTS PDF

Principal Engineer Ian Graham explores a common question in radio system design: whether to deploy duplexers or use separate transmit and. A base transceiver station (BTS) is a piece of network equipment that facilitates Antennas that relay radio messages; Transceivers; Duplexers; Amplifiers. Duplexers allow the use of a single antenna by both transmitter and receiver, coupling the transmitter and receiver to the antenna while producing isolation.
