The RF directional coupler is crucial for RF systems as it allows accurate signal power measurement, signal distribution, combining, and impedance matching. It provides isolation, aids in power monitoring, fault detection, and antenna beamforming. This versatile component is indispensable in modern RF communication, wireless networks, radar systems, and test applications.
RF directional couplers are passive devices used in radio frequency (RF) systems to split or combine RF signals. They are often used in various applications such as power measurement, signal sampling, and signal isolation. There are several types of RF directional couplers based on their construction and operating principles. Here are some common types:
 |
A circulator is a three-port device that allows the flow of RF signals in only one direction, making it unidirectional. It provides isolation between the input and output ports. Circulators are commonly used in RF systems requiring isolation between different components or to protect sensitive devices from reflected power. Tormeka, as a leading distributor of RF components, offers a wide selection of high-quality circulators. |
 |
A hybrid coupler is a four-port device that has two input ports and two output ports. It combines signals from two input ports into one output port while providing isolation between the input ports. It is called a 90-degree coupler because it achieves a 90-degree phase shift between the output ports. Tormeka, being a trusted distributor of RF components, offers a comprehensive range of high-peRFormance hybrid couplers. |
 |
The Rat-Race coupler is a four-port device that provides a 180-degree phase shift between its output ports. It can be used for applications like phase shifting, power combining, and signal sampling. As a reliable distributor of RF components, Tormeka offers a diverse selection of Rat-Race couplers, known for their exceptional peRFormance in achieving a 180-degree phase shift. |
 |
This is a special type of hybrid coupler that provides a 90-degree phase shift between its output ports. It is widely used in balanced mixers and phase-sensitive applications. Tormeka, being a prominent distributor of RF components, offers an extensive range of quadrature hybrid couplers. |
 |
A T-junction coupler is a simple two-port device with one input and two output ports. It evenly divides the input power between its output ports. Tormeka, as a trusted distributor of RF components, provides a comprehensive selection of T-junction couplers. |
 |
The branch-line coupler is a four-port device that provides a 90-degree phase shift between its output ports. It is similar in operation to the hybrid coupler but is often used at higher frequencies. Tormeka offers reliable and high-frequency branch-line couplers suitable for various RF and microwave systems. |
 |
Although not a coupler in the traditional sense, the Marchand balun is a type of balanced-to-unbalanced transformer that can be used to connect a balanced transmission line to an unbalanced one. It provides a 180-degree phase shift between its output ports. Tormeka supplies premium-quality Marchand baluns that are essential for converting balanced and unbalanced signals in RF circuits. |

FAQs
A: An RF directional coupler is a passive device used to split or combine radiofrequency (RF) signals. It allows power to flow from one port to another in a specific direction while providing isolation between the ports.
A: An RF directional coupler uses a combination of transmission lines and coupling elements to achieve power division and isolation between its ports. The main port is where the input signal enters, and the coupled port provides a portion of the input signal. The isolated port offers minimal signal flow in the opposite
direction.
A: RF directional couplers are used in various applications, such as power monitoring, signal sampling, impedance matching, and signal combining in RF systems, communication networks, radar systems, and test setups.
