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.

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.

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.

High Power Directional Coupler: HC Series

High Power Directional Coupler: HC Series

Directional Couplers isolate, separate, and combine signals in RF/Microwave measurement applications. The signal passes between the input and output ports, with a smaller portion of the initial signal passing to the coupling port. The coupling signals are isolated from the output port in order to prevent reflection.

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 Power Dual Directional Couplers: HDL Series

High Power Dual Directional Couplers: HDL Series

The HDL Series of High Power Dual Directional Couplers covers the 0.01-6000 MHz frequency range and features flat frequency response, custom coupling values from -6 to -70 dB, monitoring high power amplifiers, and more.

Quadrature Couplers and Hybrids

Quadrature Couplers and Hybrids

Wireline® and Wirepac® quadrature couplers and hybrids are ideal for applications involving diplexers, digital broadcast transmitters, power dividers/combiners, IFF, directional couplers, single balance mixers, and 3 dB quadrature hybrid couplers.

90 Degree Hybrid Octave Couplers - Lumped Element

90 Degree Hybrid Octave Couplers - Lumped Element

MCLI Hybrid couplers are four-port directional couplers designed for a 3 dB power split. They’re available in two configuration types, 90 degree (or quadrature hybrid couplers), and 180 degree hybrid couplers.

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.
