Couplers

PRODUCTS AND SERVICES

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.

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.

The CE20-0240 is a next generation broadband 2GHz to 40GHz, 20dB directional coupler from the Marki Elite Series. Conductive paint is applied to all Elite Series products to reduce EMI/RFI leakage and susceptibility. 

Krytar's directional coupler: model 264030, enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over the Ka-Band frequency range of 26.5 to 40.0 GHz in a single, compact, and lightweight package.

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. KRYTAR’s latest addition, Model 10205006, enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over a ultra-broadband frequency range of 2.0 to 50 GHz in a single, compact and lightweight package.

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’s MLDD two-way power divider, model 6005265-TV, offers high performance over the broadband ultra-broadband frequency range of 0.5 to 26.5 GHz in a compact, lightweight package.

Model 262213, enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over the K-Band frequency range of 18.0 to 26.5 GHz in a single, compact and lightweight package. 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.
