Original Abstract Submitted
embodiments disclosed herein relate to improving an available bandwidth for a transceiver of an electronic device and to reducing a footprint of an associated integrated circuit of the electronic device. to do so, an isolation circuit is disposed between a transmit circuit and a receive circuit. the isolation circuit has first and second signal paths. a first portion of the signal propagates along the first signal path and a second portion of the signal propagates along the second signal path. a non-reciprocal phase shifter is disposed on the first signal path to shift a phase of the first portion to match a phase of the second portion and improve isolation between the transmit circuit and the receive circuit. the phase-shifted first portion may be combined with the second portion to reduce or substantially eliminate an insertion loss caused by the isolation circuit.
