Directional couplers are common microwave/millimeter wave components in microwave measurement and other microwave systems, which can be used for signal isolation, separation and mixing, such as power monitoring, source power stability, signal source isolation, transmission and reflection of sweep frequency test. It is a directional microwave power divider and an indispensable part of modern sweep reflectometer. It usually has waveguide, coaxial line, ribbon line and microstrip.
Product Application
Rf passive components are mainly applied in wireless communication system construction of the base station and indoor distribution system. Especially in the building indoor wireless signal distribution covers the application of a wide range of large Numbers. Rf passive components in the base station construction and indoor distribution project have the effect of rf signal connection or distribution. Indoor distribution system is to launch the base station signal connection or shunt by rf passive components, the cover points through the feeder for the antenna, so as to achieve continuous good indoor wireless signal coverage. Indoor distribution system mainly includes the source and day supply distribution system two parts.
Passive components is the main part of day feed system.
