SEC401-51In microwave systems, it is often necessary to divide one channel of microwave power into several channels in proportion. This is the problem of power allocation. The components that realize this function are called power distribution components or couplers, which mainly include: directional couplers, power dividers and various microwave branch devices.
An optocoupler is an electrical-to-optical-to-electrical conversion device that uses light as a medium to transmit electrical signals. 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 shell and separated from each other by transparent insulators. The pins of the light source are the input terminals, and the pins of the light receiver are the output terminals. Common light source sources are light-emitting diodes, and the light receivers are photodiodes, phototransistors, etc. There are many types of optocouplers, the most common ones are photodiode type, phototransistor type, photoresistor type, photocontrolled thyristor type, photoelectric Darlington type, integrated circuit type, etc. As shown in Figure 1 below (the appearance includes metal round shell packaging, plastic packaging dual in-line, etc.).
