Duplexer - Wikipedia
: What Is It And How Does It Work?

Antenna duplexer is an essential electronic component that is used in radio communication systems to allow bi-directional or duplex communication over a single path. It enables transmitting and receiving signals on the same frequency band without interference, thus optimizing the use of a common antenna and facilitating efficient communication.

In technical terms, a duplexer is an electronic circuit that separates the transmitter and receiver signals and directs them to and from the common antenna. This function helps to isolate these signals from each other, preventing them from interfering with each other.

There are different types of duplexers available, and their selection depends on the specific needs of the communication system. Some duplexers are based on frequency and use waveguide filters to enable bi-directional communication on a single frequency band. Other duplexers use timing and polarization to facilitate duplex communication. Orthomode transducers are examples of duplexers that use polarization to separate signals, while radar systems use timing-based duplexers to permit bi-directional communication.

One of the most common applications of antenna duplexers is in repeater systems. These systems are used to extend the range of radio communication by placing a repeater station between two communication points. The repeater system receives the incoming signals, cleans and amplifies them, and then re-transmits them to the receiving end. This process is repeated in reverse for outgoing signals. Antenna duplexers play a crucial role in such systems by enabling bi-directional communication on a single antenna.

Antenna duplexers are also used in other applications such as wireless communication, satellite communication, cellular networks, and more. They are integral components of many radio communication systems, and their importance cannot be overstated.

In conclusion, an antenna duplexer is an electronic circuit that enables bi-directional communication over a single path in radio communication systems. It separates transmission and reception signals from each other, prevents interference, and optimizes the use of a common antenna. It is a vital component of many radio communication systems, and its selection depends on the specific needs of the communication system.
