MegaPhase offers a variety of directional couplers, power dividers/combiners, and quad hybrids in narrow band and ultra-broadband designs ranging from 0.5 MHz to 46 GHz. 

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.

Broadband Directional Coupler: Model 110067006 Broadband Directional Coupler: Model 110067006

KRYTAR, Inc. introduces a new broadband directional coupler, Model 110067006, with 6 dB coupling over the 10-67 GHz frequency range. With a multi-purpose, stripline design, the new coupler offers superior performance ratings including nominal coupling (with respect to output) of 6 dB, and frequency sensitivity of ±0.75 dB up to 50 GHz, and ±1.50 dB up to 67 GHz.

Wideband Directional Couplers Through 46 GHz Wideband Directional Couplers Through 46 GHz

MegaPhase offers directional couplers with a large array of coupling values and bandwidths through 46 GHz to suit various applications and system needs. Tight tolerances on coupling value, directivity, and insertion loss can be achieved in various packages and connector combinations. These RF couplers are designed for applications ranging from the most benign laboratory environments to the rigorous demands of military airborne and space systems. 

Low PIM Components Low PIM Components

Bird offers low PIM components designed to help distribute signals efficiently throughout venues, without the need to create intermodulation products. These devices are able to handle high RF power levels while minimizing interference.

L-Band Couplers L-Band Couplers

ETL Systems offers L-band (850-2150 MHz) directional couplers featuring 10 dB or 20 dB with DC, and 10 MHz pass between input and transmit ports. These devices are available in 50 Ω SMA, N-type, BNC and 75 Ω BNC or F-type RF connector options, and have coupled ports that are DC blocked.

180° Hybrid Coupler: AH180-020180 180° Hybrid Coupler: AH180-020180

The AH180-020180 from AtlanTecRF is a stripline hybrid coupler covering the 2 – 18 GHz frequency range. It provides 180 degree phase shift, and in-phase outputs from two combined signals with a maximum amplitude unbalance of ± 1.2 dB, and maximum phase unbalance of 12 degrees.

Surface Mount Directional Couplers Surface Mount Directional Couplers

Dielectric Labs Inc. (DLI) introduces a series of surface mount directional couplers designed to offer a turnkey surface mount solution for high frequency incident and reflected power monitoring. These directional couplers span the C, X, and Ku band frequency spectrums, and are available with 10dB and 20dB coupling values, and a common footprint for maximum flexibility.

ABOUT

Couplers

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.
