Abstract
A wide-band hybrid network, in which a signal received from a four-wire section is applied to a first balanced amplifier and a second balanced amplifier. The output of the first balanced amplifier is applied to one opposed terminals of a main bridge circuit which has an arm including terminals connected to a wide-band two-wire transmission line. The output of the second balanced amplifier is applied to one opposed terminals of an auxiliary bridge circuit which has an arm substantially equivalent to the impedance of the wide-band two-wire transmission line. A differential amplifier is employed for receiving signals of respective other opposed terminals of the main bridge circuit and the auxiliary bridge circuit. The output of the differential amplifier is applied to another four-wire section.
