  • Unidirectional Couplers
    Unidirectional couplers are 3-port devices that have a main line input and output and a coupled line that has a coupled output and an internal termination on the 4th port. Power passing from input to output is coupled to the coupled output and any reflected power from the main line output

  • Bidirectional RF Couplers
    Bidirectional RF couplers are four-port devices that are similar to unidirectional RF couplers, but have the termination removed from the fourth port. Main line power is coupled to the forward output of the secondary line, and reflected power is coupled to the reflected output. In order
