【Abstract】 The purpose of this paper is to describe the design of our RF generator with crystal controlled frequency which consists of the crystal oscillator,the frequency multiplier, the buffer amplifier, the power amplifier and the automatic power control. In addition, this paper also describes the principle of measuring incident and reflected power with the directional coupler and the method of calibrating power.更多还原
