90 Degree Hybrid Coupler: HB-57 90 Degree Hybrid Coupler: HB-57

MCLI introduces the HB-57 90 Degree Hybrid Coupler designed for military, commercial, and space applications within the 1 to 12 GHz frequency range. The coupler handles up to 50 Watts of average power, and up to 2 kW of peak power. Key features include an insertion loss less than 1.6 dB, isolation over 15 dB, and SMA connectors.

20-1000 MHz, 250 W CW Dual Directional Coupler: Model C10561 20-1000 MHz, 250 W CW Dual Directional Coupler: Model C10561

The new Model C10561 from Werlatone is the first coupler in a new series of 20 to 1000 MHz, Mismatch Tolerant® 50 dB Dual Directional Couplers. The coupler is rated at a conservative power of 250 W CW, and outperforms competition by operating at approximately thirty percent the insertion loss, and sixty five percent less heat dissipation in a smaller package.

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.
