Abstract
Circuits, devices and methods are disclosed, including a phase shifter configured to provide a bypass state, a single first-handed quarter-wave state, a double first-handed quarter-wave state, or a single second-handed quarter-wave state utilizing two or less inductors. In some implementations, a phase shifter is disclosed to provide a first node and a second node, a first switchable path having a first inductance and a second inductance arranged in series between the first and second nodes, a capacitive grounding path implemented on each side of each of the first and second inductances, at least one of the capacitive grounding paths configured as a switchable capacitive grounding path, and a reconfiguring circuit assembly configured to allow the phase shifter to provide a plurality of quadrant phase shifts utilizing the first and second inductances and the at least one switchable capacitive grounding path.
