Abstract: A phase shifter element includes: a first signal path and a second signal path extending in parallel between an input node of the phase shifter element and an output node of the phase shifter element; at least one first signal path e-fuse in the first signal path; and at least one second signal path e-fuse in the second signal path. The phase shifter element is programmable to select one of the first signal path and the second signal path. The phase shifter element has a first phase shift when the first signal path is selected and a second phase shift, different than the first phase shift, when the second signal path is selected.
