Phase Shift Unit

A system comprising:

• a phase shifter including:
• a first phase shift unit corresponding to a first phase shift amount, the first phase shift unit including means for shifting a phase of a signal with a pi-type circuit topology using a transistor that is configured to selectively contribute a parasitic capacitance to an inductive-capacitive core (LC core) of the first phase shift unit;
• a second phase shift unit coupled to the first phase shift unit, the second phase shift unit corresponding to a second phase shift amount;
• and
• a third phase shift unit coupled to the first phase shift unit, the third phase shift unit corresponding to a third phase shift amount.

A method for operating at least one phase shift unit, the method comprising:

• responsive to a deactivation signal being applied to a phase shift unit, turning a transistor on;
• and
• propagating a signal through the transistor in an ON state to transit the signal through the phase shift unit;
• and
• responsive to an activation signal being applied to the phase shift unit, turning the transistor off;
• and
• transiting the signal through the phase shift unit with the transistor in an OFF state to contribute a parasitic capacitance to an inductive-capacitive core (LC core) of the phase shift unit, including shifting a phase of the signal using the LC core.

A phase shift unit, comprising:

• a transistor having a first terminal connected to an input of the phase shift unit and a second terminal connected to an output of the phase shift unit;
• a first inductor having a first terminal connected to the first terminal of the transistor and having a second terminal directly connected to a ground network;
• and
• a second inductor having a first terminal connected to the second terminal of the transistor and having a second terminal directly connected to the ground network.
