TIME DIVISION DUPLEX TRANSMISSION/RECEIPT SYSTEM FOR SIMPLIFYING ISOLATION

摘要

A time division duplex transceiving system for simplifying an isolating process is provided to simplify the size of the time division duplex transceiving system and to perform filtering/isolating of signal simultaneously. A time division duplex transceiving system for simplifying an isolating process includes a switching unit, a couple line filter(204), a diode(206), and a bias controller(216). The switching unit transmits a signal transmitted from a transmitting stage to an antenna during a transmitting mode and transmits the signal received from the antenna to a receiving stage during a receiving mode. The couple line filter(204) is installed inside of the receiving device and has a plurality of combining lines to filter the signal transmitted to the receiving device. At least one diode(206) is connected to one end of at least one combining line of the couple line filter(204). The bias controller(216) controls a bias applied to the diode(206).
