Patent attributes
Embodiments disclosed herein relate to reducing or substantially eliminating an insertion loss caused by isolating a transmit circuit from a receive circuit of an electronic device. To do so, an isolation circuit may be disposed between the transmit circuit and the receive circuit. The isolation circuit may have a first signal path and a second signal path. A first portion of the signal may propagate along the first signal path and a second portion of the signal may propagate along the second signal path. A phase shifter may be disposed on the first signal path to shift a phase of the first portion to match a phase of the second portion. 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.
