Abstract
A communicate device includes transmitters and a receiver. The first transmitter is coupled to a first 90° phase shifter that is also coupled to a first antenna, and to a second 90° phase shifter that is also coupled to a first node. The second transmitter is coupled to a third 90° phase shifter that is also coupled to a second antenna, and to a fourth 90° phase shifter that is also coupled to the first node. The receiver is coupled to a fifth 90° phase shifter that is also coupled to the first antenna, and to a sixth 90° phase shifter that is also coupled to the second antenna. A non-reciprocal element, coupled between the receiver and the first node, provides a 90° phase shift from the receiver to the first node and a −90° phase shift from the first node to the receiver.
