Low Loss Microwave Directional Coupler 3db Rf Directional Coupler
1 About RF Directional Coupler : RF Directional coupler is a universal microwave/millimeter wave
component, which can be used for signal isolation, separation and
mixing, such as power monitoring, source output power stability,
signal source isolation, transmission and reflection of the sweep
test.The main technical indexes are directivity, standing wave
ratio, coupling degree and insertion loss.
