Do You know how you can Classify a Coupler?

Within the microwave system, there's often a need of one path from the microwave power becoming divided into a couple of paths, which is the issue of power allocation. The elements of realizing this function are known as power splitting components, namely, couplers, primarily such as the directional coupler, the energy divider and also the numerous microwave branching devices.

Directional coupler is really a type of component of 4 ports with directional transmission traits, that is composed of two pairs of transmission systems that are linked together by the coupling device.( Threaded Coupler, Threading Machine)

Double waveguide directional coupler is the most easy waveguide directional coupler, and each the main and auxiliary waveguides realize coupling by the two little holes around the public narrow wall. Double waveguide directional coupler would be to depend on the mutual interference of the wave to realize the directional output of primary waveguide, and also the exact same phrase may be overlaid at the coupling port, the reversed phase may be offset in the isolation port. In order to improve the coupling degree of directional coupler, and broaden the working frequency band, multi-hole directional coupler can be utilized.

Double branch directional coupler is composed of primary line, sub line and two branch lines, among which the length and the spacing of branch line are 1/4 from the center wavelength.

The parallel coupled micro strip directional coupler is a kind of reverse directional coupler, whose coupling output is within the exact same side with the main input.

The isolator can also be known as reverse device, when the electromagnetic wave passes through it in forward path, there is nearly no attenuation, and when the electromagnetic wave passes via it in reverse path, there is very big attenuation. The common isolator has two kinds: resonant mode and field shifting kind.

Photoelectric coupler is a type of electric-light-electric converter using the light because the medium to transmit electrical signal. It's composed of two components: light supply and light receptor. The light supply and also the light receptor are assembled in the exact same closed shell, and also the transparent insulator is utilized to isolate one another. The pin of light source is input terminal, and also the pin of the light receptor will be the output terminal, the typical light supply for the light-emitting diode, and the light receptor is photosensitive diode, photosensitive transistor, and so on. there are many types for photoelectric coupler, which frequently consists of photoelectric diode, photoelectric triode, photosensitive resistance type, optically controlled thyristor type, photoelectric Darlington kind, integrated circuit type etc.

According to the material and processing technologies, there are many couplers, such as Rebar couplers, Threaded coupler, Reinforcing Bar Coupler, Steel bar coupler, Tapered Thread Coupler, Cold Extrusion Coupler.
