Directional Couplers: Octave Model NF (C-NF Series)

Directional Couplers: Octave Model NF (C-NF Series)

MCLI’s Octave Model NF (C-NF Series) directional couplers feature low insertion loss, a miniature size, high directivity, high reliability, low VSWR, and more. Various type N male connector configurations are also available. This series covers the 0.225-12.75 GHz range.

2.0 to 40.0 GHz Directional Couplers: 102040020/K

2.0 to 40.0 GHz Directional Couplers: 102040020/K

These multi-purpose, stripline designed directional couplers operate over the 2.0 to 40.0 GHz frequency range and are ideal for broadband electronic warfare (EW) systems, and commercial wireless systems. More specifically, these couplers are designed to provide solutions in signal monitoring, antenna beam forming, cable distributed systems, and military/EMC environments.

3dB Hybrid Couplers: TEMline™ Series

3dB Hybrid Couplers: TEMline™ Series

API Technologies’ TEMlineTM series of 3dB hybrid couplers have an average power rating of 1000W and are normalized at 1GHz. They also feature 1 dB maximum unbalance and 90 degree phase differential between outputs. They’ve been designed to meet MIL-E-5400 Class 3 and are screenable to MIL-P-23971, making them an ideal solution for telecommunications and radar applications.

90 Degree Stripline Hybrid Couplers

90 Degree Stripline Hybrid Couplers

MCLI’s 90 Degree Stripline Hybrid Couplers are four-port directional couplers designed for a 3 dB power split. They’re RF shielded and feature high isolation, a miniature size, low VSWR, low loss, and temperature stability.

Broadband Directional SMA Couplers: CB Series

Broadband Directional SMA Couplers: CB Series

Directional couplers have at least three ports; an input, output, and coupling port. A signal passes between the input and output ports, and a small portion of that signal power applied to the input then passes to the coupling port. The coupling signals are isolated from the line output port to prevent reflections.

High Power Couplers: 25-1,000 Watts

High Power Couplers: 25-1,000 Watts

These high power couplers are available from 25-1000 watts and collectively cover up to 6000 MHz. They're ideal for hiw power test and measurement equipment, medical equipment, and amplifiers.

Ultra-Broadband Directional Couplers: 101040020/K

Ultra-Broadband Directional Couplers: 101040020/K

These directional couplers feature excellent coupling over the 1-40 GHz frequency range and are ideal for signal monitoring/measurement, antenna beam forming, cable distributed systems, military and EMC testing, and other electronic warfare (EW) systems and commercial wireless applications.

Lumped Element Directional Couplers: CL Series

Lumped Element Directional Couplers: CL Series

MCLI’s CL Series of lumped element directional couplers covers the 0.1-1300 MHz (SMA) and 0.1-850 MHz (NF) frequency ranges and features high directivity, high quality, and low VSWR. This series has an operating temperature range of -55oC to + 85oC.

ABOUT

Couplers

In electrical circuits there are three basic types of coupling for electricity. There is the restive coupling, the hard wire coupling as well as the natural conductor coupling. These couplings have different advantages and different uses in electricity and electromagnetic uses. Specific to electromagnetic coupling in the induction field, is the electro dynamic coupler, the electrostatic coupler and wave coupling. Couplings used in electromagnetic situations differ with the type of electromagnetic environment. If it’s radiation, then radio couplings are used as well as microwave couplings.

The use of couplings in electrical circuits is something that has been stable for a very long time. They are used to connect to functional circuits for the purpose of tying their energy together or to form a bridge in an effort to share the energy source. The noun comes from the railway industry where two carriages are said to be coupled by a coupling so that they may share the engine pull. In this case the transfer of energy is in series where the engine pulls the first car; the first car is coupled to the second car and is pulled by the first and so on down the line until it gets to the brake van. Coupling is the simple concept of sharing energy, just like in the train example.

In the use of electromagnetic couplers, they are more than likely to be shielded so that no magnetic force is leaked and that it is made from conductive elements inside and resistive materials on the outside in addition to their shielding. Coupling technology has been advancing over the last decade where couplings have been brought successfully into the optical industry for fiber optic coupling as well as the nanotechnology industry for particle coupling.
