Abstract:
1. A device comprising: a first hybrid configured to generate a first pair of output signals based on splitting power received via a first pair of input signals, wherein a first input of the first hybrid is coupled to an output of a first amplifier and wherein the first amplifier is configured to receive a first input signal; a second hybrid configured to generate a second pair of output signals based on splitting power received via a second pair of input signals, wherein a first input of the second hybrid is coupled to an output of a second amplifier and wherein the second amplifier is configured to receive a second input signal; a first phase shifter having only one single output signal and configured to receive the first input signal and to output the single output signal corresponding to a first phase shifted signal that is phase shifted by a first amount from a phase of the first input signal, wherein an output of the first phase shifter is coupled to an input of a third amplifier, and wherein an output of the third amplifier is coupled to a second input of the second hybrid; and a second phase shifter configured to receive the second input signal and to output a second phase shifted signal that is phase shifted by a second amount from a phase of the second input signal, wherein an output of the second phase shifter is coupled to an input of a fourth amplifier and wherein an output of the fourth amplifier is coupled to a second input of the first hybrid.
