As a piece of hardware, RF directional couplers are widely used in various transmission and communication systems. CPL-5221-20-TNC-79 is one of the most commonly used RF directional couplers in the market. This article will take a look at the application field and working principle of CPL-5221-20-TNC-79, and discuss its features and advantages.

The application field of CPL-5221-20-TNC-79 is mainly used in wireless communication systems, such as base stations, mobile terminals, wireless LANs, etc. It can be used to detect the signal level of RF signals from antenna ports, and its port isolation performance is relatively good. In addition, the performance of the frequency is also very stable, and the frequency range of 5-3000 MHz is very wide. It is suitable for various complex environments in the communication world.

When it comes to the working principle of the CPL-5221-20-TNC-79, it is based on the principle of electromagnetic coupling. The continuous signal is received by the directional coupler through the signal transmission line, and then the main wave signal and the subsidiary wave signal are transmitted to the output port. The main wave signal is transmitted to the antenna, and the subsidiary wave signal is transmitted to the measuring device, such as oscilloscope, to observe the power between the two connected lines.

In addition, the CPL-5221-20-TNC-79 has several advantages. Firstly, it offers excellent port isolation performance due to its isolation factors reaching -55dB to -85dB. Secondly, its frequency range is wide and stable, so it can meet the needs of different environments and occasions. Thirdly, it is very easy to install, and it can be used in combination with other components to form a complete signal measurement system. Moreover, it is also a cost-effective product, which is very suitable for various commercial and industrial uses.

In summary, CPL-5221-20-TNC-79 is a kind of RF directional coupler which has a wide range of applications in wireless communication systems, and is characterized by excellent port isolation performance, wide and stable frequency range, easy installation and cost-effectiveness. Therefore, it is highly recommended for various commercial and industrial uses.
