The 50C-070-XX from JFW is a wideband directional coupler designed to operate from 500 MHz to 18 GHz and is rated for 50 Watts of RF input power.
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.
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’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 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 158030 ultra-broadband directional coupler is designed for applications operating within the 0.5 to 8.0 GHz frequency range where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. These include wireless designs and many test and measurement applications from UHF through C-Band including electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments.
KRYTAR's Model 504020006 dual-directional coupler delivers 6 dB of coupling over the 4 GHz to 20 GHz range in a single, compact, and lightweight package. With a multipurpose, stripline design, it is capable of monitoring forward and reflective power in power sampling and measurement, amplifier leveling, VSWR monitoring, field control, and amplifier load and protection applications.
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.

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.
