- a second output terminal said coupled when the coupler operates in power divider mode and phase shifter, or said isolated, connected to an impedance, for example 50 ohms, when the coupler operates in power combiner mode.
- the coupler When the hybrid coupler operates according to the power divider mode, the coupler is adapted to receive an input signal on the first input terminal and to distribute, for example equally, the power of the input signal on the first input terminal. and second output terminals. It should be noted that signals delivered on the first and second output terminals have a phase shift, for example of 90 degrees.
- the coupler When the hybrid coupler operates according to the power combiner mode, the coupler is adapted to receive a first input signal on the first input terminal and a second input signal having a phase shift, for example 90 degrees, relative to at the first input signal on the second coupled input terminal, and delivering on the first output terminal the combination of the powers of the first and second input signals.
- the second isolated output terminal is coupled to an impedance, for example 50 ohms. It should be noted that the power recombination at the first output terminal is constructive while the power recombination at the second output terminal is destructive because of the phase shift between the two input signals.
- the coupler When the hybrid coupler operates in the phase-shifter mode, the coupler is adapted to receive an input signal on the first input terminal.
