Coaxial directional coupler 10 dB H-Style 694-2700 MHz 7-16 female


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 10 dB H-Style 694-2700 MHz 7-16 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).

Outstanding RF characteristics, best possible passive intermodulation and VSWR

The Coaxial directional coupler 10 dB H-Style 694-2700 MHz 7-16 female enables you to transmit high-frequency signals reliably and flawlessly with optimum protection of your sensitive equipment in a power range up to 1000 W with maximum passive intermodulation (IM3) of -160 dBc.

The protection class is IP 68.

It supports the use of the following frequency bands : 700, 800, 900, 1500, 1800, 2100, 2300, 2400, 2600

The 7-16 connector has become the most widely used coaxial connection system for mobile communication systems, due to its excellent mechanical and electrical properties. In order to achieve the industry leading intermodulation performance SPINNER applies silver-plating on all inner and outer conductor parts of the standard connector. As a supporting measure, we use exclusively non-magnetic materials, and we have minimized the number of RF contact points. The connection is especially suited for transmitting medium or high power indoors and outdoors.

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.

  • H-style directional couplers typically have a horizontal layout, with the input and output ports aligned along a straight line, resembling the letter 'H' in their configuration.
  • In H-style couplers, the coupled and isolated ports are usually positioned perpendicular to the mainline, forming the arms of the 'H'.
  • These couplers are often used in applications where space constraints are less of a concern, as they tend to occupy a larger footprint due to their layout.

Invest in our high-performance directional couplers to elevate the performance and reliability of your broadcast or mobile communication system. Trust in our expertise and commitment to delivering superior RF components for your broadcasting needs. Overall, this directional coupler offers a simple and cost-effective solution for your installation.
