TRANSMISSION/RECEIPT SIGNAL ISOLATING DEVICE OF COMMUNICATION SYSTEM

摘要

PURPOSE: A transmission/receipt signal isolating device of a communication system is provided to isolate the multiplex transmission/receipt signals into two paths using a general circulator and isolators frequently used in an RF system. CONSTITUTION: Multiplex signals are flowed in one direction by a circulator(10). The first isolator(20) receives the signals of the circulator(10), and shields signals which can be input to a circuit by being reflected from a port A. The second isolator(30) transmits the signals to the circulator(10), and shields the receipt signals applied to a port B. The first isolator(20) and the second isolator(30) are respectively connected to loads. That is, the receipt signals are connected to the port A, and the transmission signals are connected to the port B.
