.RF Directional Coupler
XC0450A-03S is the latest type of RF directional couplers. This type of directional coupler is based on a passive network technology, which is used to measure and manipulate radio frequency signals. It features a high performance and wide dynamic range, as well as excellent power control over an extended frequency bandwidth.
Application field
XC0450A-03S is widely applied in a variety of fields. In radio circuits, the directional couplers allow to measure the transmission intensity of antenna and reception signal intensity of a signal\'s receiver without changing the existing system condition. The directional coupler compares transmitted power level and reception power level directly. Besides, it can also be applied in the test and measurement field for automatic gain control, power measurement, and impedance matching of RF signals.
Working principle
XC0450A-03S working principle is based on the power-splitting principle. It is operated in the forward direction (input to output). An input signal is fed through an input port and then split up into three different components using a two-port network. The most important of these is the coupled port, which carries a fraction of the power of the original signal, depending on the coupling value. This signal is then transferred to an output port via a third port called the termination port, which is usually set to a very low impedance.
The coupler has three separate ports, the input port, the output port and the coupled port. An input signal is fed to the input port and then splits up into three different components using a two-port network. The coupled port carries a fraction of the power of the original signal, depending on the coupling value. This is then transferred to the output port via a third port, called the termination port, which is usually set to a very low impedance. When the input signal is removed, the output port still carries the same fraction of the signal as the coupled port, as the coupler is balanced and symmetrical.
XC0450A-03S is a passive device and is usually not affected by the signals it is coupling, as the coupling takes place without introducing any additional frequency or amplitude distortion. The main benefit of the coupler is that it enables the measurement and control of the magnitude of the signal at a point in the circuit without having to modify it. This means it can be used to measure power and other parameters from existing circuits, such as the antenna, without having to disconnect and reconnect the device.
Conclusion
XC0450A-03S are widely used in the radio engineering, test and measurement field, and are an effective device for automatic gain control, power measurement, and impedance matching. Their easy installation and operation make them a popular and versatile choice.
