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.

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.

180 Degree SMA Hybrid Couplers

180 Degree SMA Hybrid Couplers

Hybrid couplers can be used to split signals from tower top amplifiers to BTS receivers, in signal sampler applications to monitor system performance, to inject a signal into a system without interrupting its service, in the creation of reflecting phase shifters, and more.

Directional Coupler Octave Model-SMA (C Series)

Directional Coupler Octave Model-SMA (C Series)

The C Series of directional couplers by MCLI feature low VSWR, a miniature size, low insertion loss, high directivity, and high reliability. This line covers the 0.225-19.5 GHz frequency range.

Directional Couplers: 698-2700 Series

Directional Couplers: 698-2700 Series

This series of directional couplers covers the 698-2700 MHz frequency range. Four different models are available with varying frequencies, coupling, insertion loss, and more.

High Power Dual Directional Couplers: HD Series

High Power Dual Directional Couplers: HD Series

This series of dual directional couplers is ideal for signal measurement applications in the 0.5 to 11 GHz frequency range. They feature monitoring high power amplifiers, custom coupling values from -30dB to -50dB, and a flat frequency response.

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.

High-Performance and Ultra-Broadband Directional Couplers

High-Performance and Ultra-Broadband Directional Couplers

KRYTAR’s 152610, 152616, and 152620 directional couplers cover the 0.5 GHz to 26.5 GHz frequency range. They’re ideal for applications with space constraints because of their small size. They’d be well-suited for use in signal monitoring and measurement, EMC testing, antenna beam forming, and cable distributed systems.

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.
