Abstract

PURPOSE:To enhance the impedance (as evaluated from the transmission line side) of a carrier control device in its non-transmission state and thereby to improve the reliability of signal transmission, by inserting an analog switching circuit in between the carrier signal amplifier and the transmission line.
