Directional couplers are most frequently constructed from two coupled transmission lines set close enough together such that energy passing through one is coupled to the other. This technique is favoured at the microwave frequencies where transmission line designs are commonly used to implement many circuit elements. However, lumped component devices are also possible at lower frequencies, such as the audio frequencies encountered in telephony. Also at microwave frequencies, particularly the higher bands, waveguide designs can be used.

350/380-3800MHz N Female Directional Coupler
Rf passive devices are mainly used in base station construction of wireless communication system and indoor distribution system. In particular, there are many kinds and a large number of applications in the indoor distribution coverage of no-line signals in buildings. Rf passive devices play the role of connecting or distributing RF signals in base station construction and indoor distribution engineering. Indoor distribution system is to connect or branch the signals transmitted by the base station through rf passive devices, and disperse them to the antenna of each coverage point through feeders, so as to achieve good continuous coverage of indoor wireless signals.
