本文提出了一种新的介质腔振荡器(DRO)光调谐方法及电路。利用GaAS光敏材料在激光照射下电导的变化,调节变容管两端的偏压,在3.4GHz得到了32MHz的光调谐范围,而DRO的输出的功率只有很小的变化。
A new method and annovel circuit of the optically tuned DRO are pressented. The optical input changes the conductance of a GaAs photosensitive sample which causes the inverse voltage of the varactor diodes to be regulated
resulting in a shift of the central frequency of the DRO. The optical tuning range 32 MHz in 3. 4 Ghz has been obtained with a little change in output power of the DRO.
