IBSC REPEATER USING TELEPHONE LINE

摘要

PURPOSE: An IBSC repeater using a telephone line is provided to simply install a repeater without an additional work by simultaneously supplying the repeater supply power and RF signals using the existing telephone line. CONSTITUTION: A telephone line(40) connects a base station(21) with an IBSC repeater(100). A matching device(23) is provided between the output end of the base station(21) and an IF filtering part(24), and matches the impedance on the telephone line(40) with the impedance on the IBSC repeater(100). A part for dividing synthetic signal(22) divides IF signals and power signals that are transmitted through the telephone line(40) from the base station(21). The part for dividing synthetic signal(22) consists of a capacitor for transmitting the only IF signals to the matching device(23) and reactance for passing the only DC power to a power(33).
