Abstract :
In many applications, the linearity of microwave amplifiers is a very important property. The optical illumination of MESFET amplifiers can be used for improving the linearity. Our recent investigations show that the application of a proper termination at the gate-source port for the light induced current and the optimum adjustment of light intensity give a significant improvement in both linearity and intermodulation distortion.
