DISTRIBUTED ANTENNA SYSTEM FOR TIME DIVISION DUPLEX

摘要

According to an example embodiment of the inventive concept, a master unit for time division duplex includes a passive signal distributor for outputting, to a second node, a downlink signal input through a first node, and outputting, to the first node, an uplink signal input through a third node, and a signal transceiver for transmitting, to a remote unit, the downlink signal input from the second node, and outputting, to the third node, an uplink amplification signal received from the remote unit.

1. A master unit for time division duplexer, comprising:
a passive signal distributor configured to output, to a second node, a downlink signal input through a first node, and output, to the first node, an uplink signal input through a third node; and a signal transceiver configured to transmit, to a remote unit, the downlink signal input from the second node, and output, to the third node, an uplink amplification signal received from the remote unit, wherein the passive signal distributor includes a circulator.
