Directional Coupler-parameter
Directional coupler is widely used in cellular communication system, it could  make the allocation of signal power according to a certain proportion  .Directional couplers are mainly used in mobile communication and broadcast systems, or as a measuring device for coupling out signals for monitoring they are the key components in in-building systems.  The lightweit design allows easy attachment to a wall using the supplied bracket. 


Application : 
1. Mobile Communication Network Optimization and In-door and out-door distribution system.
2. Wireless coverage solution ,Antenna systems and subsystem. 
3. Cluster communication, satellite communication, shortwave communication and hopping radio.
