  • Switchable active balanced-to-unbalanced phase shifter
    Patent number: 10819321
    Abstract: Disclosed is a phase shifter capable of achieving 360° phase shifts. The phase shifter includes an active balanced-to-unbalanced (balun) circuit for splitting an input signal into two signals offset in phase. The phase shifter further includes an active all-pass network electrically coupled to an output of the active balun circuit. The active all-pass network can include an active tunable inductor. A variable-gain amplifier (VGA) is electrically coupled to an output of the active all-pass network.
