Couplers

PRODUCTS AND SERVICES

The OLH2047, OLH2048, and OLH2049 are dual-channel, hermetic 8-pin DIP optocouplers designed especially for high reliability applications that require optical isolation with high CTR and low saturation VCE.

50C-064-XX is a wideband directional coupler with SMA female connectors.  This model operates 375-6000 MHz and is rated for 50 Watts of RF input power.  This model has three ports:  Input Port, Output Port, and Coupled Port.  Due to its reactive directional design, it couples in one direction only.

KRYTAR 180° hybrid couplers feature dual input and output ports that offer wide frequency coverage in single, compact packages, which provide low insertion loss, high directivity, and tight coupling. 

The MCT4 and MCT4R products are designed especially for high-reliability applications that require optical isolation with high Current Transfer Ratio (CTR) and low saturation VCE. Each optocoupler consists of an LED and N-P-N silicon photo-transistor that is mounted and optically coupled in a four-leaded hermetic TO–18 package.

Krytar coaxial Dual-Directional Couplers are 4-port couplers that are the combination of two 3-port couplers having their main lines cascaded. This design lets you monitor forward and reflected power.

KRYTAR’s model 101065016 directional couplers offer the ultimate solution for emerging designs and test and measurement applications including mmWave and 5G.

KRYTAR’s directional couplers are uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission, and reflection measurements are required.

ABOUT

In electrical circuits, there are three basic types of coupling for electricity. There is restive coupling, hard wire coupling, and 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.
