There is provided a phase shifting device and method of manufacturing the same. The device comprises an auto-transformer comprising a primary winding configured to receive an input signal; and two secondary windings, wherein a first one of the two secondary windings is in phase with the primary winding and a second one of the two secondary windings is out of phase with the primary winding. The device also comprises a first switch coupled to an output signal of the first one of the two secondary windings of the auto-transformer; and a second switch coupled to an output signal of the second one of the two secondary windings of the auto-transformer. Output signals of the first and second switches are couplable to an output of the phase shifting device.
