Background

Multiplexers are the generic name for devices such as duplexers, triplexers, and quadplexers. The multiplexer has a single input port and a plurality of output ports. The multiplexer is a set of non-overlapping filters that in combination ensure no loading of each other and a high degree of isolation between the outputs.

A duplexer, also called an antenna duplexer, is a special two-way three-terminal filter. The duplexer couples weak received signals and feeds larger transmitting power to the antenna, and requires that the two perform their functions independently without affecting each other. The general duplexer is composed of a spiral vibration shell, because the working frequency is high, the influence of distribution parameters is large, a sealing sleeve body is usually made, all signal feeder lines are coaxial cables with good shielding effect, the shape and the material of the shell also require certain smoothness, the appearance is usually black for facilitating heat dissipation, and three signal ends generally adopt the requirements of standard high-frequency connector Q9 or L16 type high-frequency socket wireless communication on the duplexer.
