1. A transceiver comprising:
a first amplifier having a first signal input;
a second amplifier having a second signal input;
a first transformer electrically coupled to the first amplifier;
a second transformer electrically coupled to the second amplifier;
a first switching network having a first switch and a second switch, and being electrically coupled to the first transformer, the first switching network configured to activate the first switch to apply a first phase shift to the first signal input of the first amplifier, and activate the second switch to apply a second phase shift to the first signal input of the first amplifier; and
a second switching network having a third switch and a fourth switch, and being electrically coupled to the second transformer, the second switching network configured to activate the third switch to apply the first phase shift to the second signal input of the second amplifier, and activate the fourth switch to apply the second phase shift to the second signal input of the second amplifier.
