RF Directional Couplers, although small in size, plays an important role in many communication devices. Here, we will take 1B0680-3 as an example to talk about its application field and working principle.

1B0680-3, a well-known RF Directional coupler, is typically used in point-to-point communication systems, where an RF signal needs to be transmitted from one end to the other. Primarily used in bridges and routers, this device allows the signal to travel both ways in order to complete the transmission.

In addition, 1B0680-3 is widely adopted in cellular base stations due to its excellent performance in splitting the transmitted signal from the received one. This device will help base stations to filter out the received signal and abort any interfering signals.

Besides, 1B0680-3 is also used in Wi-Fi networks and local circuits as well. Physically, this device is a coaxial line and features several conducting cartons and capacitors as well as resistors to control the flow of the signals.

Now, let’s get into the working principle of 1B0680-3. The RF directional coupler is designed to gather some of the power from the port where it is connected and “sample” it to the other port. This is done by magnetically coupling a portion of the signal to the other port.

In this regard, the two ports of the device work independently. As there is no direct connection between the two ports, there is no need to worry about the imbalanced performance due to the mutual junction between them. Therefore, the device can be used in a point-to-point communication system where the transmission needs to be stable and reliable.

In conclusion, 1B0680-3 is an important RF Directional Coupler which enjoys a wide range of applications. It offers great performance and convenience, making it very popular for different communication uses. It is also simple to operate and easy to install, making it the perfect device for many communication systems.
