ABSTRACT:
A switching circuit is made by serially connecting two field effect transistors in series in a small-signal transmission path, each of the transistors being applied with a substantially equal voltage, so as to lower a voltage applied to each of the FETs in the OFF state by voltage division, with the result that a high withstand voltage of the transmission path can be attained and a linear output can be obtained even when a large electric power is transmitted.
