| Multihole Directional Couplers |
Description
Directional couplers are used to sample power flowing in waveguides. The power so tapped is called coupling factor or coupling in dB. These are designed using Microwave CAD software. These are available in 3, 6, 10 and 20 dB coupling. It consists of two wave guide, joined with their broad wall. The main wave guide is straight and fitted with flanges at both ends. The auxiliary wave guide has 90° bend at one end in E plane and another end is fitted with suitable matched load. The common broad wall of both wave guides has a row of coupling holes. The diameter and number of holes in a row and number of rows varies accordingly to coupling factor required. |

| Cross Directional Coupler |
Description
This is another type of directional coupler. It differs from multihole directional coupler in some manners, two waveguide joined with their broad wall makes an exact 90 cross. Thus any two consequent ports has 90deg angle with each other. All four ports are fitted with flanges.

| Waveguide Tapered Transitions |
These are used to interface waveguides of different mechanical dimensions but overlap each other in frequency range.
Description
The frequency limits are based upon cutoff frequency of smaller waveguide and the frequency at which the second mode will propagate in the large waveguide. The units are continuous taper design to achieve lowest possible VSWR.
To meet customers’ multiple require in mobile communication, satellite communication, military, radar, medical…, we supply high performance flexible twistable waveguide, which have standard connection and jacket, or as per customers’ request. |
