Abstract:
A device includes a first hybrid, where a first input of the first hybrid is coupled to an output of a first amplifier configured to receive a first input signal. A first input of a second hybrid is coupled to an output of a second amplifier configured to receive a second input signal. The device includes a first phase shifter configured to receive the first input signal and a second phase shifter configured to receive the second input signal. An output of the first phase shifter is coupled to an input of a third amplifier, and an output of the third amplifier is coupled to a second input of the second hybrid. An output of the second phase shifter is coupled to an input of a fourth amplifier, and an output of the fourth amplifier is coupled to a second input of the first hybrid.
