1J0560-3

RF directional couplers are an important component used in radio frequency (RF) circuit design. They can be used for measuring the power of a certain frequency as well as for passing signal energy from one place to another by providing impedance matching. One of them is 1J0560-3 RF Directional Coupler, which references the industry standard of N type connector assemblies.

Generally speaking, 1J0560-3 RF directional coupler features low insertion loss and high directivity, which maximizes its value for applications such as amplifiers, filters, antennae, mixers, and receivers. It has an N female connector on each side with an N male connector in the center. An internal ground system ensures good performance in terms of directivity, VSWR, insertion loss and intermodulation distortion.

Application field of 1J0560-3 RF directional coupler typically includes, but not limits to, high-power communication system，telecommunication link, broadcast system, distributed antenna system, base station, data processing and communication system, satellite communication system, mobile communication system, and WLAN systems.

As for the working principle, the 1J0560-3 RF directional coupler directs a portion of the energy at the input of an antenna, amplifier, or other device to be coupled and diverted to an output port for monitoring or other applications. It functions by taking a portion of the power from the input port or side and sending it towards the output side through the use of an internal transformer. This allows the output power to be equal to a certain fraction of the signal that is being input. The internal transformer also helps to match the impedance of the directional coupler to that of the device being used.

To sum up, 1J0560-3 RF directional coupler is one of the most common RF components that can be found in various applications. It is a versatile device, which provides low insertion loss and high directivity, making it ideal for use in high-power communication system, distributed antenna system, base station, data processing and communication system, and mobile communication system. With the help of its internal transformer, this directional coupler can transfer a portion of the power from the input to the output port while providing impedance matching.
