Couplers
PRODUCTS AND SERVICES
KRYTAR’s model 101065016 directional couplers offer the ultimate solution for emerging designs and test and measurement applications including mmWave and 5G.
Skyworks, through its wholly-owned subsidiary Isolink, provides screened and hermetically sealed high-reliability optocouplers, RF diodes, and RFICs, including multi-chip modules (MCM) for aerospace, defense, medical, extreme industrial and high-reliability markets and applications.
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.
The C10-1000WG is a WR10 10dB waveguide coupler featuring high directivity over a 75-100GHz operational bandwidth built with high precision and then gold plated for high corrosion resistance.
KRYTAR's 4-50 GHz directional couplers are crafted for system applications necessitating external leveling, precise monitoring, signal mixing, or swept transmission and reflection measurements.
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.
Krytar’s Model 101065016 enhances the selection of multi-purpose, stripline designs that exhibit excellent coupling over a ultra-broadband frequency range of 1.0 to 65 GHz in a single, compact, and lightweight package.
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.
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.
