X3C09A2-03S

A radio frequency (RF) directional coupler is an electrical device that is used to receive, detect and measure radio frequency signals embedded within a transmission line. It is a passive device, which means it is not powered and relies on an external power source for its operation. The X3C09A2-03S directional coupler is an extremely wideband directional coupler for a wide range of frequency bands. It supports the frequency range from 7.5 to 13.75 GHz and is typically used in applications such as cellular base station and distributed antenna system (DAS). In addition, the X3C09A2-03S is designed to provide very low insertion loss, excellent directivity and satisfies the variability of its operation in the given frequency range.

The working principle of X3C09A2-03S RF directional coupler is based on the transfer of energy, between the main line and a coupled line. Two identical conductors, such as other RF components like stubs, baluns, or transformers, are connected to form a directional coupler. The two conductors are tied together at one end and the other end are fed with the RF signal. The signal then travels through the two conductors, and the energy is transferred between them, forming the directional coupler. The amount of energy transferred between the two conductors depends on the distance between the two, as well as the type of material used. The amount of energy transferred can be determined by measuring the power level at the output of each conductor.

The operating frequency range of the X3C09A2-03S is very wide with frequency range of 7.5 to 13.75 GHz. This wide frequency range makes it suitable for use in applications such as cellular base station and distributed antenna system (DAS). The directional coupler’s wide frequency range makes it an ideal device for measuring and detecting radio frequency signals of different frequencies. In addition, the coupler is also designed to provide low insertion loss ensuring efficient transmission of signals. The RF impedance of 50 Ohm is also maintained across the wide range of applications of this directional coupler. The directivity of the device is also impressive with typical directivity of 30 dB.

In addition to the wide frequency range, the X3C09A2-03S provides other useful features like excellent isolation between direct and reverse ports. The reverse port isolation is typically greater than 20 dB at the most extreme frequency. The coupler also provides stable performance across the entire frequency range and is designed to be temperature tolerant. The temperature tolerant design ensures that the coupler remains stable over a wide environmental range. The X3C09A2-03S is also designed to be easy to install with a simple two port connection. Once connected, the device can be used to receive, detect and measure radio frequency signals in order to monitor and maintain the performance of the communication system.
