High-Performance Directional Couplers for radio frequency networks

A directional coupler is a passive component used in radio frequency (RF) systems to split or combine RF signals while maintaining the directional flow of the signal. Its primary function is to transfer a portion of the RF power flowing in one transmission line to another transmission line, typically with minimal loss.

Directional couplers operate based on the principle of electromagnetic coupling between transmission lines. They consist of at least four ports: the input port (usually called the main line), the output port (also known as the through port), and two auxiliary ports (the coupled port and the isolated port.

When an RF signal is applied to the input port, a portion of that signal is coupled to the coupled port while the majority of the signal continues through to the output port. The amount of power coupled to the auxiliary port is determined by the design of the directional coupler and is typically specified as a coupling factor in decibels (dB).

Directional couplers are essential components in broadcast stations or mobile communication networks. Couplers enable engineers to monitor signal strength, analyse performance, and distribute signals to various components within the broadcast or communication system. Use cases are:

  • Signal Monitoring: Directional couplers allow RF engineers to monitor signal strength and quality at various points within the RF system, ensuring optimal performance.
  • Signal Measurement: They facilitate accurate measurement of RF signals for troubleshooting, maintenance, and performance optimization.
  • Signal Distribution: Directional couplers enable the distribution of RF signals to multiple components or devices within the transmission line without significant signal loss.
  • Isolation: They provide isolation between the input and output ports, minimizing interference and ensuring signal integrity.
  • Versatility: SPINNER directional couplers are available in various designs and frequency ranges, making them suitable for a wide range of broadcast or mobile communication system applications.

The Coaxial directional coupler 3 dB X-Style 300 W 694-2700 MHz N female guarantees excellent, lossless mobile communication quality for use in in-building distributed antenna systems (DAS) or on mobile communication base stations outdoors.

SPINNER directional couplers are characterized by highly effective signal isolation and extremely low intermodulation (low PIM).

The N-coaxial connectors were named after their inventor Paul Neill, who developed this standard for RF connectors in 1942. Often, however, the name also relates to the Navy Connector. Type N connectors can be used at frequencies up to 11 GHz, high-precision types up to 18 GHz. It is typically used in mobile communication applications with demanding mechanical and electrical requirements. SPINNER exclusively manufactures connectors with non-slotted outer conductor contacts and a special sealing profile in the connector head instead of the flat seal disk, specified by IEC or CECC. This ensures the most reliable sealing function.

The terms 'H-style' and 'X-style' directional couplers refer to different configurations or layouts of directional couplers based on the physical arrangement of their internal components.

  • X-style directional couplers have a diagonal or crisscross layout, resembling the letter 'X' in their configuration.
  • In X-style couplers, the coupled and isolated ports are typically arranged diagonally across the mainline, intersecting at a central point.
  • X-style couplers are known for their compact design and efficient use of space, making them suitable for applications where size and footprint are critical considerations.

In terms of functionality and performance, both H-style and X-style directional couplers operate on the same principles of electromagnetic coupling and signal separation. The choice between the two styles often depends on factors such as available space, installation requirements, and system design preferences. Each style offers advantages in certain scenarios, and engineers may select the most appropriate style based on the specific needs of their RF system.
