Abstract:
1. An RF pulse signal generation switching circuit for controlling an output of a power FET for amplifying a high frequency signal to generate an RF pulse signal that is the high frequency signal pulse formed into a pulse-wave shape, comprising: first and third n-type FETs of which gates are inputted with a control pulse generated by a controller, wherein the control pulse supplies a rise timing and a fall timing of a pulse; and a second n-type FET of which a gate is connected with a drain of the first FET, wherein a source of the first FET and a source of the third FET are grounded, respectively, wherein the drain of the first FET is supplied with a first drive voltage via a resistor, wherein a drain of the second FET is supplied with a second drive voltage, wherein a source of the second FET is connected with a drain of the third FET via a connection point and said connection point between the source of the second FET and the drain of the third FET is connected with the power FET, and wherein a capacitor is connected between said connection point and an end of the resistor from which the first drive voltage is supplied.
