XC0450L-03S

Radio-Frequency (RF) directional couplers measure power in radio frequency signals, while allowing them to remain un-interrupted and follow its transmission path. Directional couplers are used for a variety of applications including impedance matching, antenna measurement, power monitoring, power control, and general RF test measurements. The XC0450L-03S is one of the most popular directional couplers for applications ranging from 200-400MHz.

The XC0450L-03S directional coupler works by sampling the forward power of an RF transmission line and provides a sample output, which can be used for various applications. The XC0450L-03S consists of two main components: a ferrite core coupling and a substrate material, on which the element is built. The substrate material typically consists of two layers of polyimide, in which the cores are embedded.

The ferrite core coupling acts as a parametric converter, which takes in incoming signals in the form of radio waves and converts them into approximately 90 degree circular diverging signals. These signals are then sampled by the substrate material and routed to the output port. The output port is usually a 50 ohm matching resistor, which is used to match the impedance of the two signal paths.

The XC0450L-03S is ideal for a wide range of applications due to its high power handling capacity and wide working frequency range. It can be used for power measurement, antenna measurement, impedance matching, as well as general signal energy monitoring. The XC0450L-03S directional coupler can also be used in a variety of power supply applications such as AC, DC, 12V and 24V mains.

The XC0450L-03S directional coupler can be incorporated in any RF system in order to measure signal power without interrupting its continuous input and output. It is a reliable and accurate device for a variety of applications ranging from RF measurements and power monitoring to antenna measurements and power control. The XC0450L-03S is one of the most popular directional couplers in its class and is an excellent choice for any application where precise and efficient power measurements are needed.
