常用的红外接收头主要由CX20106、μpc1373等,外加阻容元件、红外接收管、滤光片及金属屏蔽罩组成,一般体积较大。新一代红外接收模块RPM638已将红外接收管、前置放大、解调电路集成在问一基片上,具有体积小,无需外加元件,抗光电干扰,接收角宽,价格低等优点,目前已在一些国外电器产品中使用。RPM638采用树脂封装,有直立、卧式两种型式。RPM638-CBR-S为直立侧面受光型,内部原理见图1,外形见图2。RPM638可直接与LC2190/LC2200(6路自锁或互锁)、BL9148/BL9150(18路)、BA5104/BA5204(8路:2路自锁6路持续)
Commonly used infrared receiver mainly by CX20106, μpc1373, etc., plus RC components, infrared receiver tube, filter and metal shield, the general size larger. The new generation of infrared receiving module RPM638 has integrated the infrared receiving tube, preamplifier and demodulation circuit into one substrate, which has the advantages of small volume, no external components, anti-optical interference, wide receiving angle and low price. At present, Used in some foreign electrical products. RPM638 resin package, a vertical, horizontal two types. RPM638-CBR-S is upright side of the light-receiving type, the internal principle shown in Figure 1, the shape shown in Figure 2. The RPM638 can work directly with the LC2190 / LC2200 (6-way self-locking or interlocking), BL9148 / BL9150 (18 ways), BA5104 / BA5204
