Abstract
Official abstract text for this publication.
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 is provided. The circuit includes first and third n-type FETs of which gates are inputted with a control pulse that 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. A source of the first FET and a source of the third FET are grounded, respectively. The drain of the first FET is applied with a first drive voltage via a resistor. A drain of the second FET is applied with a second drive voltage. A source of the second FET is connected with a drain of the third FET and the connection point therebetween is connected with the power FET. A capacitor is connected between the connection point and an end of the resistor from which the first drive voltage is applied.
First claim
Opening claim text (preview).
What is claimed is: 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…
