Abstract :
This paper reports experimental results of optical control of millimeter-wave HJFET MMIC oscillators and FET model parameter analysis with illumination. Using a noncoherent optical source, the maximum optical tuning ranges of 32 MHz around 30 GHz and 260 MHz around 51 GHz were obtained. By means of parameter extraction, a 46.6% increase in Cgd and a 19.1% decrease in Cds due to the illumination and their frequency dependence were appreciated.<>
