RF Directional Couplers are common devices in the electronic world. They are widely used in radio telecommunication systems, broadcasting systems, microwave communication systems, satellite communication systems, wireless communication systems, mobile communication systems, and so on. The 1C0870-20 RF Directional Coupler is one of the most commonly used RF Directional Couplers. This article will discuss its application field and working principle.

Applications of 1C0870-20 RF Directional Coupler

1C0870-20 RF Directional Couplers are used in a variety of applications. In radio telecommunication systems, they are used for signal routing, signal monitoring, interference suppression, and power combining. In broadcasting systems, they are used for sound-reinforcement systems, and they can even be used in the feedlines of antennas. They are also used in microwave communication systems for signal routing and for power combining, and they are also used in satellite communication systems for signal routing and interference suppression. In wireless communication systems and mobile communication systems, they are used for combining and routing high-power signals.

Working principle of 1C0870-20 RF Directional Coupler

The working principle of 1C0870-20 RF Directional Coupler is quite simple. It consists of a coaxial cable connected to two ports, which are connected to the input port and the output port. The output port is connected to an antenna, while the input port is connected to an antenna of a different frequency. Both the input port and the output port are connected to a circulator. The circulator is an electronic device that passes current in one direction only. When a signal is transmitted from the input port, it will travel through the coaxial cable and be reflected off the circulator. The reflected signal will then travel back through the coaxial cable and be received by the output port. This reflected signal is known as the coupled signal.

The 1C0870-20 RF Directional Coupler can be used to measure the magnitude of the coupled signal. The amount of power coupled to the output port is determined by the strength of the reflected signal, which is determined by the length of the coaxial cable, the type of circulator used, and the frequency of the incoming signal. In addition, the 1C0870-20 RF Directional Coupler can also be used to measure the gain of the system, which can be used for signal monitoring and power combining applications.

Conclusion

In conclusion, the 1C0870-20 RF Directional Coupler is a commonly used device in radio telecommunication systems, broadcasting systems, microwave communication systems, satellite communication systems, wireless communication systems, and mobile communication systems. Its working principle is quite simple, as it consists of a coaxial cable connected to two ports, which are connected to the input port and the output port. The output port is connected to an antenna, while the input port is connected to an antenna of a different frequency. The 1C0870-20 RF Directional Coupler can be used to measure the magnitude of the coupled signal, as well as the gain of the system.
