三点式振荡器是指LC回路的三个端点与晶体管的三个电极分别连接而成的电路，如图4-1（a）所示。图中三个电抗元件X1、X2、X3构成了决定振荡频率的并联谐振回路，同时也构成了正反馈所需的反馈网络。从相位条件看，要构成振荡器，必须满足： (1)极相连的两个电抗X1、X2性质相同。 (2)X1与X2、X3的电抗性质相反。-three-point refers to LC oscillator circuit with three transistors endpoint of three electrodes were connected with the circuit, Figure 4-1 (a) below. Figure 3 reactor components X1, X2, X3 decision constitutes a frequency of the oscillation parallel resonant circuit, but also constitutes a positive feedback for the feedback network. From Phase conditions, to constitute an oscillator, to be met : (a) very connected to the two reactor X1, X2 the same nature. (2) X1 and X2, X3 nature of the resistance-- contrary.
