Folded Network
When the number of inlets is equal to the number of outlets for a switching network, such a network is called the Symmetric Network, which means N=M. A network where the…
Basics of a Switching System
In this section, we will learn about the different components and terms used in switching systems. Inlets and Outlets The set of input circuits of an exchange are called Inlets and the…
Telecommunication Network
A Telecommunication network is a group of systems that establishes a distant call. The switching systems are part of a telecommunication network. The switching stations provide connection between different subscribers.…
Switching Systems
A Switching system can be understood as a collection of switching elements arranged and controlled in such a way as to set up a common path between any two distant…
Two-Hole Directional Coupler
This is a directional coupler with same main and auxiliary waveguides, but with two small holes that are common between them. These holes are λg/4λg/4distance apart where λg is the guide…
Directional Couplers
A Directional coupler is a device that samples a small amount of Microwave power for measurement purposes. The power measurements include incident power, reflected power, VSWR values, etc. Directional Coupler is a…
Rat-race Junction
This microwave device is used when there is a need to combine two signals with no phase difference and to avoid the signals with a path difference. A normal three-port…
E-H Plane Tee
An E-H Plane Tee junction is formed by attaching two simple waveguides one parallel and the other series, to a rectangular waveguide which already has two ports. This is also…
H-Plane Tee
An H-Plane Tee junction is formed by attaching a simple waveguide to a rectangular waveguide which already has two ports. The arms of rectangular waveguides make two ports called collinear ports i.e.,…
E-Plane Tee
An E-Plane Tee junction is formed by attaching a simple waveguide to the broader dimension of a rectangular waveguide, which already has two ports. The arms of rectangular waveguides make…
