In a microwave system, it is often necessary to divide a microwave power into several paths in proportion, which is a power distribution problem. The components that implement this function are called power distribution components, ie, couplers. Defibrillation testers mainly include: directional couplers, power splitters, and various microwave branch devices. An optocoupler is an electric-optical-electrical conversion device that transmits electrical signals by means of light. It consists of two parts: a light source and a light receiver. The light source and the light receiver are assembled in the same sealed casing and separated from each other by a transparent insulator. The pin of the light source is the input end, and the pin of the light receiver is the output end. The common light source is a light emitting diode, and the light receiver is a photodiode, a phototransistor, and the like. There are many types of photocouplers, such as photodiode type, phototransistor type, photoresistor type, light control thyristor type, photoelectric Darlington type, integrated circuit type, etc. As shown in Figure 1 (the shape has a metal round shell package, plastic double row inline, etc.)
