一般的红外接收头主要由CX2016A，PC1373等集成电路外加阻容元件，红外线接收管及滤波光片等组成，因而体积较大。而新一代一体化红外遥控接收头SFH506-38与RPM-638CBR将红外接收管，前置放大解调等电路集成在同一基片上，内电路框图如图1所示，具有体积小，无外部元件，抗干扰性能好，接收角度宽、价格低等优点。-General infrared receiving mainly CX2016A, PC1373 external RC components such as integrated circuits, infrared-ray receiving tube and filter etc., and therefore larger. The new generation of integrated remote control receiver head SFH506-38 and RPM-638CBR the infrared receiver control, demodulation, etc. preamplifier integrated circuits on the same substrate, in the circuit diagram shown in Figure 1, is small, no external components anti-interference performance, wide receiver perspective, the price is low.
