Scientific knowledge-Difference between combiner and multiplexer
2021-01-31
In fact, there are so many customers in other countries will understand the combiner and the Multiplexer as the same thing, but there is a some difference between them.
1.Multiplexer is a collective term for such devices as duplexer, triplexer and quadruplexer.The multiplexer has a single input port and multiple output ports.The combiner generally has two or more input ports and only one output port.
2.The main function of the combiner is to combine the input signals of multiple frequency bands and output them to the same indoor distribution system.so it will be used more in the BTS.
while The multiplexer is a set of non-superimposing filters. These filters are combined to ensure that they do not load each other, and the outputs are highly isolated.the cutomized multiplexer will be used more inside on the equipment.
3.The duplexer is composed of two (transceiving) filters combined, sharing a common node (antenna), allowing the device to transmit (Tx) and receive (Rx) at the same time.while the combiner Each port is both a transmitting port and an input port,only mention the frequency on each port.

Antennas are an indispensable part of radio communication systems. Although the tasks of various radio equipment are different, the functions of antennas are basically the same. One is to radiate and receive electromagnetic waves; the other is to convert energy, converting the high-frequency oscillating current of the transmitter into high-frequency electromagnetic waves for radiation, and vice versa when receiving. The higher the antenna gain, the higher the conversion efficiency.
