Key Parameters of RF Directional Couplers

RF directional couplers, also called RF couplers, provide simple means of monitoring or sampling RF energy.
A RF directional coupler has four ports, one is the input port on the main line, one is the through port also on the main line(the amount of output power is reduced according to the coupling value.), one is the coupled port (a fix percentage of the input power is coupled to this port), and one is the isolation port  which is usually connected to termination.
The key parameters of a RF directional coupler are: 
Coupling value:  coupling value is the amount of power diverted to the coupled output from the input port.
Insertion loss:  insertion loss describes the losses due to coupling.
Isolation:  isolation indicates the degree of the power leakage from the main line to the isolation port.
