Abstract
A non-volatile adjustable phase shifter is coupled to a transceiver in a wireless communication device. The non-volatile adjustable phase shifter includes a non-volatile radio frequency (RF) switch. In one implementation, the non-volatile RF switch is a phase-change material (PCM) RF switch. In one approach, the non-volatile adjustable phase shifter includes a selectable transmission delay arm and a selectable transmission reference arm. A phase shift caused by the non-volatile adjustable phase shifter is adjusted when the non-volatile RF switch engages with or disengages from the selectable transmission delay arm. In another approach, the non-volatile adjustable phase shifter includes a selectable impedance element. A phase shift caused by the non-volatile adjustable phase shifter is adjusted when the non-volatile RF switch engages with or disengages from the selectable impedance element. In either approach, the phase shift changes a phase of RF signals being transmitted from or received by the transceiver.
