What is the Ortomode converter?

Orthomode converter is a passive microwave device that allows the microwave and the receiver to transmit and receive, respectively, on the same compound corner or antenna. In microwave communication circuits, the transmission line and antenna are engaged in electromagnetic (EM) wave. The Ortomod converter is mostly used on the broadcasts used by satellite data and satellite TV. At more than a few dozen Gigahertz (GHz), where 1 GHz is a billion cycles per second, a coaxial cable or transmission pipe, for connection to the antenna loses all signal in the coaxial cable. One approach is to skip the transmission line so that the microwave transmitter leads to a place where an antenna, which is usually mounted at a high height on the radio tower. It was later used as the equivalent of the transfer line, although it carries clean electricity, as well as other transmission lines. It carries EM wool, which is the same energy format as the spread of radio waves.

The

orthomod converter uses the principle that two emissions of microwaves with the same frequency will disturb if these two waves are polarized in the same way. Polarization is related to the relative position of the magnetic component of the issue. The vertically polarized issue will have a vertical magnetic field and a horizontal electric field. In addition, the orthomod converter works on two emissions of very close frequencies, where it is orthogonally or 90 degrees, separated from the second in the orientation of EM. Orthodic converters maintain orthogonal separation and allow transmitted and received signals to coexist on the same antenna.

Orthodes converters have three ports: Corner or antenna port, transmitter port and receiver port. They are equivalent to frequency duplexes that use so -called tuned radio cavities that have geometry correlated with free air geometry RF. These geometric sizes RF are referred to as wavelengths. IfD The electric field sees a conductive geometry that is a multiple of half wavelengths, simply passes, but if it sees conductive geometry, which is a special multiple of a quarter of wavelength, short -circuit.

In the wavy pipeline and in the orthomod converter, the dimension of the hollow cross -section must be a suitable function of the signal wavelength. Orthomod converter routes have transmitted energy into an antenna or feed and protect the receiver by preventing the transmitted energy from reaching the receiver. It takes the incoming signal from the feed corner and points it to the receiver. Orthodic converters also use the polarization difference for insulation of transmitted and received signals.
