Figure:The ultra-high frequency emitting module CS901 circuit composed of SAW In the figure is the ultra-high frequency emitting module CS901 circuit composed of SAW, the model of the circuit is CS901, which adds the modulator VT2 and the power supply filter circuit on the base of basic circuits. The capacitors C5~C7 and R3 compose the power supply filter circuit, which avoid the disturbance of the power supply and improve the stability of the circuit. VT2 and R2 compose the modulation circuit, which is fixed at the emitting pole of the oscillating emitter VT1, the data signal is input from V1, by the control on VT2, the digital modulation of the emitting signal is completed.
