The internal RF remote control transmitter KIA6933S is composed of pulse generator within the integrated circuit KIA6933S, the duty factor regulator, mixer, oscillator and RF carrier frequency amplifier. The remote control transmitter circuit composed of it hasmany features, such assimpleexternal rotation circuit, easy to debugging. Usually 4 states remote controls can be achieved. The internal KIA6957P receiving circuit has two low-frequency amplification units, integration circuit and signal comparison detection circuit. Since there is not high-frequency receiving circuit, it uses high-frequency super-regenerative receiver circuit. The similar types of circuits are: DF-27/DJ-27, TA7333P/TA7657P.
